for calculating molecular formula you should know atomic mass of each element in the formula
for example
H2O
H=1u
O=16u
=>molecular formula of H2O will be
2H+O
2×1+16
18u

1. Determine the empirical formula mass
EFM atomic masses multiplies respective number a verious atom present in the empirical formula.
2. divide the molar mass by EFM
3. multiply EF by n to get molecular formula
