Q: In order to determine its molecular formula, it is necessary to know what about the compound?


Read this paragraph and choose the correct option from the provided answers:

Empirical formulas can be determined from the percent composition of a compound. In order to determine its molecular formula, it is necessary to know the molar mass of the compound. Chemists use an instrument called a mass spectrometer to determine the molar mass of compounds. In order to go from the empirical formula to the molecular formula, follow these steps:.

 Choices:

- lipid mass

- polar mass

- protons mass

- molar mass


A:
molar mass
