For the conversion factors you just write one molecule/formula unit over another until you've done every conversion factor possible. The reaction occuring is Basis : 1g Na2CO3 solution and 1 g Ca(OH)2 solution Na2CO3 = 1(0.2)= 0.2 g Na2CO3 M.w of Na2CO3 = 106 g/mol Moles of Na2CO3 = 0.2/106 = 0.0018867 mol view the full answer Previous answer has the right idea, but the wrong formula. Ca(HCO3)2(aq) + Na2CO3(aq) ---> CaCO3(s) + 2NaHCO3(aq) This represents the removal of temporary hardness from water by adding 'washing soda'. Depending on the amount of Na2CO3 being added, you might also see some CO2 gas being given off as the equilibrium is shifted to the left. 2CO2 + 2H2O <==> 3H+ + HCO3- + CO3^2- But as far as going to the stockroom and getting a bottle of solid Ca(HCO3)2.

A B; sodium carbonate: Na2CO3 - strong: silver sulfate: Ag2SO4 - insoluble: ferric phosphite: FePO3 - insoluble: calcium hydroxide: Ca(OH)2 - strong: hydrochloric acid Number of moles of Ca(NO3)2 = molarity*volume = 0.45M*(50/1000)L = 0.0225 moles One mole of Ca(NO3)2 require one mole of Na2CO3, so the required number of moles of sodium carbonate = 0.0225 moles Required mass of Na2CO3 = moles*molar mass = 0.0225*105.99 = 2.39 grams of Na 2CO3 c. Assuming that the Na2CO3 has a negligible effect on the volume Nov 14, 2019 · For Na2CO3, mass = 2 * 23 + 12 + 3 * 16 = 106 grams.
