How many atoms are present in 123 g of sodium cyanide (cyanide = CN-)? A sample contains 0.687 mol H3PO3. What is the mass of H3PO3in the sample? A 2.000 g sample of Calcium sulfate dihydrate, CaSO42H2O (this is one molecule) contains 1.582 g CaSO4. How many moles of CaSO4 are there in this sample? Assuming that the rest of the sample is water, how many moles of H2O are there in the sample? How is the result consistent with the formula CaSO4·2H2O?
