Question
ompound W has the empirical formula C*H_{4}*O and a relative molecular mass of 32 Calculate the molecular formula of compound W[1]molecular formula =
Solution
The empirical formula of compound W is CH4O. The empirical formula mass of CH4O is (12.01 * 1) + (1.01 * 4) + (16.00 * 1) = 30.05 g/mol.
The relative molecular mass of compound W is given as 32 g/mol.
The molecular formula of a compound is found by dividing the relative molecular mass by the empirical formula mass.
So, 32 g/mol ÷ 30.05 g/mol = 1.06
Since the molecular formula is a multiple of the empirical formula, and 1.06 is approximately equal to 1, the molecular formula of compound W is the same as its empirical formula, CH4O.
