What is the molecular formula of the molecule that has an empirical formula of CH2Cl and a molar mass of 247.5 g/mol?

The answer to your question is Molecular formula C₅H₁₀Cl₅

Explanation:

Data

Empirical formula   CH₂Cl

Molar mass = 247.5 g/mol

Process

1.- Calculate the molar mass of the empirical formula

CH₂Cl = (12 x 1) + (1 x 2) + (35.45 x 1)

          = 12 + 2 + 35.45

          = 49.45 g

2.- Divide the Molar mass of the molecular formula by the molar mass of the empirical formula.

            247.5 / 49.45 = 5

3.- Multiply the empirical formula by the result

           5 (CH₂Cl) = C₅H₁₀Cl₅
