1) What is the molarity of a HCI solution if 28.3 mL of HCl is required to react with 0.256 g of Na2CO3 (molar mass = 106 g/mol)? Start with the grams of sodium carbonate. 2 HCl(aq) + Na2CO3(s) + 2 NaCl(aq) + H2CO3(aq) 2) Calculate the volume of a 0.156 M CuSO4 solution that would react with 7.89 g of zinc. Start with the grams of zinc. Zn(s) + CuSO4(aq) + Cu(s) + ZnSO4(aq) 3) What volume (in milliliters) of 0.1M AgNO3 would be needed to completely react with 2.50 g zinc? Start with the grams of zinc. Zn(s) + 2 AgNO3(aq) + 2 Ag(s) + Zn(NO3)2(aq)
