Two elements and have atomic weights of 14 and 16. They form a series of compounds and in which for the same amount of element , the element is present in the ratio . If the compound has 28 parts byweight of and 16 parts by weight of , then the compound of will have 28 parts weight of and
32 parts by weight of
48 parts by weight of
64 parts by weight of
80 parts by weight of
Given,
For the same weight of element , ratio of weights of in compounds and = 1 : 3
Thus, in the compound , the weight of present is
