The empirical formula of the compound containing 9.39 g of phosphorus and 0.61 g of Hydrogen is  PH₂

Data obtained from the question

  • Phosphorus (P) = 9.39 g
  • Hydrogen (H) = 0.61 g
  • Empirical formula =?

How to determine the empirical formula

The empirical formula of the compound can be obtained as follow:

Divide by their molar mass

P = 9.39 / 31 = 0.303

H = 0.61 / 1 = 0.61

Divide by the smallest

P = 0.303 / 0.303 = 1

H = 0.61 / 0.303 = 2

Thus, the empirical formula of the compound is PH₂
