Question

The empirical formula for a compound was determined to be SCl, and the molar mass for the compound was 135 g/mol. Find the molecular formula

Answer 1

for molecular formula we have to find

= $\frac{M}{mm}$

M = mass of the compound = 135 g/mol

mm = molar mass of SCl =67.51 g

= $\frac{135}{67.51}$ = 2

the molecula formula of the compound is

S₂Cl₂
