Calculate the molecular formula of a compound with the empirical formula CH O and a molar mass of 150 g/mol. A) C2H4O2

B) C3H6O3

C) C4H8O4

D) C5H10O5

E) C6H12O6

The molecular formula : D) C₅H₁₀O₅

Given

The empirical formula CH₂O

The molar mass of 150 g/mol

Required

The molecular formula

Solution

The empirical formula is the smallest comparison of atoms of compound forming elements.  

A molecular formula is a formula that shows the number of atomic elements that make up a compound.  

(empirical formula) n = molecular formula  

(CH₂O)n = 150 g/mol

(12+2.1+16)n = 150

(30)n = 150

n = 5
