Answer:
Molecular formula = C₄F₈Explanation:
Given data:
Empirical formula of compound = CF₂
Molar mass of compound = 200.4 g/mol
Molecular formula of compound = ?
Solution:
Formula:
Molecular formula = n ( empirical formula)
n = Molar mass of compound / empirical formula mass
empirical formula mass = CF₂ = 12+19×2 = 50 g/mol
n = 200.4 g/mol / 50 g/mol
n = 4
Molecular formula = n ( empirical formula)
Molecular formula = 4 ( CF₂)
Molecular formula = C₄F₈
