Suppose that we found pieces of mineral pyrite in two different locations around the world. The first sample with mass of 2.50g contained 1.16g of iron and 1.34g of sulfur. The second sample with mass of 5.2g contained 2.4g of iron and 2.8g of sulfur. Which law do these results support? Law definite proportions Law of multiple proportions Dalton Law Law of conservation of mass
