Question

Determine the molecular formula of an oxide of iron in which the mass percent

Answer 1

Answer:

the empirical formula is Fe2O3 ...

the molar mass of the empericcal formula is the same

Answer 2

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.
