Question

12. Determine the molecular formula of an oxide.of
iron in which the mass percent of iron and
oxygen are 69.9 and 30.1 respectively. Given
that molar mass of the oxide is 159.898 mol-1​

Answer 1

Answer:

Determine the molecular formula of an oxide of iron in which the mass per cent of iron and oxygen are 69.9 and 30.1 respectively. Therefore the empirical formula of the oxide is Fe2O3. =0.999 = 1(approx.) Molecular formula of a compound is obtained by multiplying the empirical formula with n.
