Suppose that your instructor gives you two samples and claims that they are both aluminum phosphide (AlP). Through a series of tricky chemical reactions, your instructor has you decompose both samples into the constituent aluminum and phosphorous, and you weigh each of your sample components on the analytical balance. You find that one sample produced 3.85 g Al and 4.42 g P, while the other produced 3.05 g Al and 3.94 g P. Are these results consistent with the law of constant composition  Face with Open Mouth

Sample 1: 6.3 g Ca/2.54 g S = 2.5

Sample 2: 3.4 g Ca/1.90 g S = 1.8

Answer: No, the results of the ratio between the two samples is different, therefore they are not consistent with the law of constant composition.
