A 5.235.23 g sample of calcium sulfide was decomposed into its constituent elements, producing 2.912.91 g of calcium and 2.322.32 g of sulfur. Which of the statements are consistent with the law of constant composition (definite proportions)? The ratio of calcium to sulfur will vary based on how the sample was prepared. Every sample of calcium sulfide will have 2.91 g of calcium. The mass ratio of SS to CaCa in every sample of calcium sulfide is 0.80. Every sample of calcium sulfide will have 55.6% mass of calcium. The mass percentage of calcium plus the mass percentage of sulfur in every sample of calcium sulfide equals 100%.
