You analyzed 2.475 of a mixture of NaCl, SiO2 and CaCO3. You isolate .825g NaCl, .825g of CaCO3 and .580 g SiO2. You were told that the original mixture contained 35% NaCl, 45% CaCO3 and 20% SiO2. Calculate, compare, and offer an explanation for the differences in the composition of NaCl, CaCO3 and SiO2 you recovered. Explain.
