what is the maxium number of grams of ph3 that can be formed when 6.2 g of phosporus reacts with 4.0 g of hydrogen to form ph3
Weegy: moles P4 = 6.2 g/ 123.895 g/mol=0.050 moles H2 = 4.0 g/ 2.016 g/mol=2.0 ( in excess) moles PH3 = 0.050 x 4=0.20 mass PH3 = 0.20 mol x 33.9978 g/mol= 6.8 g User: in a particular reaction between copper metal and silver nitrate, 12.7 g of Cu produced 38.1 g of Ag. what is the percent yield of silver in this reaction?

hydrogen gas is produced when zinc reacts with hydrochloric acid. If the actual yield of this reaction is 85%, how many grams of zinc are needed to produce 112 L of h2 at STP
Weegy: Hydrogen gas is produced when zinc reacts with hydrochloric acid. [ [ If the actual yield of this reaction is 85%, 380 g of zinc are needed to produce 112L of H2 at STP. -Start with a balanced chemical equation Zn + 2 HCl - > ZnCl2(aq) + H2 112L H2 x (1 mol H2 / 22.4 L H2) x (1 mol Zn / 1 mol H2) x (65.4 g Zn / 1 mol Zn) = 327 g Zn But that is if you had 100% yield. Only 85% of the Zn that was present produced H2, so divide 327 by 0.85 to get the beginning mass of Zn, which is 385 g. ] ] (More)
