1.) Use the equation given to solve the following problems: How many moles of AgNO3 would be required to react with 1.0 mol of Na3PO4? How many moles of NaNO3 can be produced from 0.30 mol of Na3PO4? What weight of Ag3PO4 can be produced from 4.00 grams of AgNO3? If you have 8.44 grams of Na3PO4, what weight of AgNO3 will be needed for complete reaction? If you have 8.44 grams Na3PO4, what weight of AgNO3 will be needed for complete reaction? When 25.0 grams of AgNO3 are reacted with excess Na3PO4, 17.7 grams of Ag3PO4 are produced. What is the precentage yield of Ag3PO4?
