Answer: A (Molecular Formula)

Explanation: 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, which requires the Molecular Formula to be completed.

The empirical formula and the formula mass of a compound are needed to determine the compound's molecular formula. The correct option is a) molecular formula

Molecular formula

When the formula mass is divided by the empirical formula molar mass, and the result (a whole number or close to a whole number) is then multiplied  by all the subscripts in the empirical formula, we get the molecular formula.

Hence, the empirical formula and the formula mass of a compound are needed to determine the compound's molecular formula. The correct option is a) molecular formula
