Interpretation Introduction To determine: The empirical formula of the compound. Explanation Given: The mass of compound is 1 3 the mass of X. The atomic mass of X is 1 3 of the atomic mass of Y. Explanation: Suppose the ratio of X to Y is m : n . So, we have: m Mass X + n Mass Y = 3 Mass X Rearrange the above expression as follows: m Mass X m Mass X + n Mass Y = 1 3 Substitute Mass Y as 3 Mass X in the above expression as follows: m Mass
