Question

At one time, chemists thought that the formula of a binary compound was the simplest formula possible. For example, the chemical formula of water was thought to be HO and that of ammonia was thought to be NH.
1. Given that

Explanation / Answer

mols of O = 0.832 g / 16 g/mol = 0.052 mol mols of H = 0.104 g / 1 g/mol = 0.104 mol Deriving the empirical formula dividing by 0.052 ==> H2O since there is 2 H for each O, the atomic mass of O based on the formula HO will equal: the atomic mass / 2 = 16 / 2 = 8 amu mols of N = 0.403 g / 14 g/mol = 0.0287 mol mols of H = 0.0864 g / 1 g/mol = 0.0864 mol Deriving the empirical formula dividing by 0.0287 ==> NH3 since there is 3 H for each N, the atomic mass of N based on the formula NH will equal: the atomic mass / 3 = 14 / 3 = 4.666 amu
