Given the empirical formula C2H3O, what is the molecular formula that has a mass of 214.8g?

Given the empirical formula, the molecular formula that has a mass of 214.8g is C₁₀H₁₅O₅

From the question, we are to determine the molecular formula

From

Molecular formula = (Empirical formula)n

Where

From the given information,

Empirical formula is C₂H₃O

Therefore, Empirical formula mass = (12×2) + (1×3) + (16)

Empirical formula mass = 24 + 3 + 16

Empirical formula mass = 40 g

Then,

n = 5.37

n ≅ 5

Therefore,

Molecular formula = (C₂H₃O)₅

Molecular formula = C₁₀H₁₅O₅

Hence, given the empirical formula, the molecular formula that has a mass of 214.8g is C₁₀H₁₅O₅
