When 1g of impure calcium carbonate was was reacted to 20 cm^3 of 1M HCl acid is reacted according to the equation: CaCo3 + 2HCl to give HCl 2 + H2O +CO2 The excess acid was found to react exactly with 20cm^3 of 0.1M NaOH solution . Given that the RMM of CaCo3 is 100 , what percentage of Carbonate is 1g of the impure CaCo3
