many grams of barium phosphate can be made from the reaction of 45.00 g of
phosphoric acid and 120 g of barium acetate?
2. How
many grams of calcium carbonate are produced in the reaction between 13.70 ml
of 0.940 M calcium chloride and 4.81 x 1024 mc of lithium carbonate?
3. How
many molecules of water are produced when 16.99 g of ethane (C2H6

the percent yield of carbon dioxide if 130.00 L of the gas are produced when
1.79 x 1022 mc of sugar (C12H22O11
) burn in excess oxygen gas? (Assume
that one mole of gas = 22.4 L)
