Text Solution

Verified by Experts

Molecular mass and empirical formula are used to deduce molecular formula of the compound .
Steps to calculate molecular formula:
1. Empirical formula is found out from the percentage composition of elements
2. Empirical formula mass can be found from the empirical formula
3. Molecular mass is found out from the given data
4. Molecular formula = `("Empirical formula")_(n)`
5. where, n = `("Molecular mass")/("Empirical formula mass")`
