The multiplier (n) to get the molecular formula is equal to 8.
Given the following data:
- Empirical formula of styrene = CH.
- Molar mass of CH = 104 g/mol.
Scientific data:
- Molar mass of carbon (C) = 12 g/mol.
- Molar mass of hydrogen (H) = 1 g/mol.
How to calculate molecular formula.
First of all, we would determine the gram-mass of styrene (CH) as follows:
\(CH = 12+1\)
CH = 13 g/mol.
For the molecular formula:
\((CH)n=104\\\\13n=104\\\
=\frac{104}{13}\)
n = 8
