Given the following balanced chemical equation, what are some mole ratios we can develop? POCl 3 + 3 H 2 O H 3 PO 4 + 3 HCl 1 mole POCl 3 = 1 mole H 3 PO 4 1 mole POCl 3 = 3 moles HCl 1 mole POCl 3 = 3 moles H 2 O 3 moles H 2 O = 1 mole H 3 PO 4 3 moles H 2 O = 3 moles HCl Given the following balanced chemical equation, what are some mole ratios we can develop?

1 mol O 2 2 mol H 20 2 mol H 2 O 1 mol O 2 So if I ask how many moles of water (H 2 O) are formed if you use 215 moles of oxygen, you can use the conversion factor to determine moles of water. 215 mol O 2 2 mol H 2 O = 430 moles H 2 O 1 mol O 2
