How many grams of hydrochloric acid and required to react completely with 61.8 grams of calcium hydroxide when they produce calcium chloride and water?
2HCl+Ca (OH)2------>cacl2+2H2O ...now every 2 moles of hcl reacts with 1 mole ca (oh)2..... 2moles of hcl = 2×(36.5)=73 gm.. 1 mole of ca (oh)2=40+(17×2)=74 gm.. so ... 61.8 gm of hcl need ...(61.8×73)/74= 60.964864864
