A mixture of FeO and Fe_(3)O_(4) when heated in air to a constant weight, gains 5% of its weight. Find the composition of the intial mixutre.

A mixture of FeO and Fe_(3)O_(4) when heated in air to a constant weight, gains 5% of its weight. Find the composition of the intial mixutre.

1.84 g of a mixture of CaCO_(3) and MgCO_(3) was heated to a constant weight. The constant weight of the residue was found to be 0.96g. Calculate the percentage composition of the mixture. (relative atomic masses of Ca and Mg are 40 and 24 respectively).

On being heated in air, a mixture of Feo and Fe_2O_4 picks up oxygen to convert completely to Fe_2O_3 . If the observed weight gain is 5% of the initial weight, what must have been the composition of the initial mixture?
