Question

A compound having empirical formula  has vapour density . The molecular formula of this compound is:

Canvas Classes · Accepted Answer

Strategy:
 Vapour density is half of the molar mass (). We find the molecular formula by determining the multiplier '', which is the ratio of the molar mass to the empirical formula mass.

Step 1: Calculate molar mass
Molar mass

Step 2: Calculate empirical formula mass
Empirical formula .
Mass

Step 3: Find n and molecular formula
