Question
The empirical formula of compound is 'CH', one mole of this compound has molecular formula mass = 26 g/mol. Its molecular formula is :
Solution
The empirical formula of a compound is the simplest, most reduced ratio of elements in a compound. In this case, the empirical formula is CH, which has a molar mass of 12 g/mol for Carbon (C) and 1 g/mol for Hydrogen (H), totaling 13 g/mol.
The molecular formula of a compound can be a multiple of the empirical formula. The molecular formula mass given is 26 g/mol.
To find the molecular formula, you divide the molecular formula mass by the empirical formula mass.
So, 26 g/mol ÷ 13 g/mol = 2
This means the molecular formula is twice the empirical formula. Therefore, the molecular formula of the compound is C2H2.
