Calculate the Molar Mass of a Compound

How to Calculate the Molar Mass of a Compound

In chemistry, the molar mass of a compound is the mass of one mole of that compound. To calculate the molar mass of a compound, we need to know the mass of the compound and the number of moles present.

Given that 0.372 mol of the compound has a mass of 15 grams, we can calculate the molar mass using the following formula:

Formula:

Molar Mass (M) = Mass (g) / Number of Moles

Given Data:

Mass of the compound = 15 grams

Number of moles = 0.372 mol

Calculation:

Molar Mass = 15 g / 0.372 mol = 40.32 g/mol

Answer:

The molar mass of the compound is 40.32 g/mol. Therefore, the correct answer is B. 40.32 g/mol.

Explanation:

To calculate the molar mass of a compound from the given mass and number of moles, we divide the mass of the compound by the number of moles. In this case, when we divide 15 grams by 0.372 moles, we get a molar mass of 40.32 g/mol.

Therefore, we have successfully calculated the molar mass of the compound using the provided data.
