The empirical formula of styrene is ch; its molar mass is 104.1 g/mol. what is the molecular formula of styrene? select one:

a. c2h4

b. c8h8

c. c10h12

d. c6h6

e. none of these

b. C₈H₈

Explanation:

The empirical formula of styrene is CH. To calculate the molecular formula, we have to calculate "n", where n:

The molar mass of the empirical formula is C + H = 12.01 + 1.00 = 13.01 g/mol

The molar mass of the molecular formula is 104.1 g/mol

n = (104.1 g/mol) / (13.01 g/mol) ≈ 8

The molecular formula is:

Molecular formula = n × Empirical formula = 8 × CH = C₈H₈
