The empirical formula of Lorelai's compound is C₄H₁₀O

Data obtained from the question

  • C = 64.8 g
  • H = 13.62 g
  • O = 21.58 g
  • Empirical formula =?

How to determine the empirical formula

Divide by their molar mass

C = 64.8 / 12 = 5.4

H = 13.62 / 1 = 13.62

O = 21.58 / 16 = 1.35

Divide by the smallest

C = 5.4 / 1.35 = 4

H = 13.62 / 1.35 = 10

O = 1.35 / 1.35 = 1

Thus, the empirical formula of the compound is C₄H₁₀O
