150.0 mL of 0.2105 M nitric acid was added to 1.3415 g calcium carbonate. The excess acid was back titrated with 0.1055 M sodium hydroxide. It required 75.5 mL of the base to reach the end point. Calculate the percentage (%w/w) of calcium carbonate in the sample. HNO; + NAOH NaNO3 + H2O 2HNO3 + CaCO3- Ca(NO3)2 + H2O + CO2
