Let me know the answer to the question

7 In one experiment, 6 10 g of iron was heated and treated with
steam to obtain 8 72 g of iron(III) oxide In another experiment, 12
84 g of iron(III) oxide was reduced with hydrogen to get 8 98 g of
iron Show that these results Illustrate the law of constant
proportions

Dear student,
Experiment - 1:Mass of iron oxide obtained=8
72 gMass of iron taken =6
10 gMass % of Iron =6 108 72×100=69
95 %Experiment -2 :Mass of iron oxide taken = 12
84 gMass of iron obtained = 8
98 gMass % of Iron =8 9812 84=69
183 %Since the percentage of Iron in the two samples is same (with in 0
5%)Hence the law of definitive proportion is verified
