Understanding the Molar Mass of NaPO4

In the realm of chemistry, understanding the molar mass of compounds is crucial for various calculations and applications. The molar mass of a compound is the sum of the atomic masses of its constituent elements, expressed in grams per mole (g/mol). In this article, we will delve into the molar mass of NaPO4, a compound composed of sodium (Na), phosphorus (P), and oxygen (O).

The Composition of NaPO4

NaPO4, also known as sodium phosphate, is a compound that consists of one sodium atom, one phosphorus atom, and four oxygen atoms. The atomic masses of these elements are:

Sodium (Na): 22.99 g/mol
Phosphorus (P): 30.97 g/mol
Oxygen (O): 16.00 g/mol

Calculating the Molar Mass of NaPO4

To calculate the molar mass of NaPO4, we need to sum the atomic masses of its constituent elements. The formula for NaPO4 can be broken down as follows:

Na (1 atom) + P (1 atom) + O (4 atoms)

The atomic masses of these elements are:

Na: 22.99 g/mol
P: 30.97 g/mol
O: 16.00 g/mol (4 atoms) = 64.00 g/mol

Now, let's calculate the molar mass of NaPO4 by summing the atomic masses of its constituent elements:

Molar mass of NaPO4 = 22.99 g/mol (Na) + 30.97 g/mol (P) + 64.00 g/mol (O) Molar mass of NaPO4 = 117.96 g/mol

Comparing the Calculated Molar Mass with the Given Options

Now that we have calculated the molar mass of NaPO4, let's compare it with the given options:

A. $2,000 B. $2,500 C. $3,000 D. $3,500 E. $4,000 F. 9.96 g/mole G. 227.94 g/m

Our calculated molar mass of NaPO4 is 117.96 g/mol, which is not among the given options. However, we can see that option F, 9.96 g/mole, is close to our calculated value. However, this value is not accurate.

Conclusion

In conclusion, the molar mass of NaPO4 is 117.96 g/mol, which is not among the given options. The closest option is F, 9.96 g/mole, but this value is not accurate. Therefore, the correct answer is not among the given options.

Q: What is the molar mass of NaPO4?

A: The molar mass of NaPO4 is 117.96 g/mol.

Q: How do I calculate the molar mass of a compound?

A: To calculate the molar mass of a compound, you need to sum the atomic masses of its constituent elements. The formula for calculating the molar mass of a compound is:

Molar mass = (number of atoms of each element) x (atomic mass of each element)

Q: What is the difference between atomic mass and molar mass?

A: Atomic mass is the mass of an individual atom, while molar mass is the mass of a mole of atoms. In other words, atomic mass is a measure of the mass of a single atom, while molar mass is a measure of the mass of a large number of atoms (one mole).

Q: How do I find the atomic masses of elements?

A: The atomic masses of elements can be found on the periodic table. The periodic table is a table that lists all the known elements, along with their atomic numbers and atomic masses.

Q: What is the significance of the molar mass of a compound?

A: The molar mass of a compound is significant because it allows us to calculate the number of moles of a compound present in a given sample. This is important in chemistry because it allows us to calculate the amount of a substance present in a sample.

Q: How do I calculate the number of moles of a compound present in a sample?

A: To calculate the number of moles of a compound present in a sample, you need to know the mass of the sample and the molar mass of the compound. The formula for calculating the number of moles of a compound present in a sample is:

Number of moles = mass of sample / molar mass of compound

Q: What is the relationship between the molar mass of a compound and its density?

A: The molar mass of a compound is related to its density. The density of a compound is the mass of the compound per unit volume. The molar mass of a compound is the mass of a mole of the compound. Therefore, the density of a compound is equal to the molar mass of the compound divided by the volume of the compound.

Q: How do I calculate the density of a compound?

A: To calculate the density of a compound, you need to know the mass of the compound and its volume. The formula for calculating the density of a compound is:

Density = mass of compound / volume of compound

Q: What is the significance of the density of a compound?

A: The density of a compound is significant because it allows us to calculate the volume of a compound present in a given sample. This is important in chemistry because it allows us to calculate the amount of a substance present in a sample.

Q: How do I calculate the volume of a compound present in a sample?

A: To calculate the volume of a compound present in a sample, you need to know the mass of the sample and the density of the compound. The formula for calculating the volume of a compound present in a sample is:

Volume = mass of sample / density of compound

Q: What is the relationship between the molar mass of a compound and its boiling point?

A: The molar mass of a compound is related to its boiling point. The boiling point of a compound is the temperature at which the compound changes state from a liquid to a gas. The molar mass of a compound is the mass of a mole of the compound. Therefore, the boiling point of a compound is related to its molar mass.

Q: How do I calculate the boiling point of a compound?

A: To calculate the boiling point of a compound, you need to know the molar mass of the compound and the boiling points of similar compounds. The formula for calculating the boiling point of a compound is:

Boiling point = (molar mass of compound) x (boiling point of similar compound)

Q: What is the significance of the boiling point of a compound?

A: The boiling point of a compound is significant because it allows us to determine the temperature at which the compound changes state from a liquid to a gas. This is important in chemistry because it allows us to determine the properties of a compound.
