You take three compounds, each consisting of two elements (X, Y, and/or Z) and decompose them to their respective elements. To determine the relative masses of X, Y, and Z, you collect and weigh the elements, obtaining the following data: Elements in Compound Masses of Elements 1. X and Y, X = 0.4 g, Y = 4.2 g 2. Y and Z, Y = 1.4 g, Z = 1.0 g 3. X and Y, X = 2.0 g, Y = 7.0 g c) What are the chemical formulas of the three compounds? d) If you decompose 21 g of compound XY, how much of each element is present?

Question
You take three compounds, each consisting of two elements (X, Y, and/or Z) and decompose them to their respective elements. To determine the relative masses of X,
Y, and Z, you collect and weigh the elements, obtaining
the following data:
Elements in Compound Masses of Elements
1. X and Y, X = 0.4 g, Y = 4.2 g
2. Y and Z, Y = 1.4 g, Z = 1.0 g
3. X and Y, X = 2.0 g, Y = 7.0 g
c) What are the chemical formulas of the three
compounds?
d) If you decompose 21 g of compound XY, how much
of each element is present?
