Question

Certain compound has formula x406 10 g of compound contains 5.62 of x

Answer 1

Molecular formula of the compound = X4O610 grams ofX4O6 contains 5.72 grams of X.Percentage of X in given molecule = (5.72*100)/10Percentage of X = 57.2 %Percentage of Oxygen = 100- Percentage of X = 100- 57.2= 42.8%Gram molecular weight 6 atoms of Oxygen (O6) = 6*16 = 96 grams42.8% of Oxygen has a mass of 96 grams.Then 57.2 % of X will have a mass of = (57.2*96)/42.8= 128.29 grams4 atoms of X has a mass = 128.29 grams1 atom of X will have a mass = (128.29)/4= 32.075Gram atomic mass of X = 32.075 grams
i hope its helps u:-)
