Question

For a reaction:
2NaHCO3- Na2CO3 + H2O + CO2
2.5 g of a sample NaHCO3 when strongly heated gives 310cc of
CO2 gas at 27°C and 760 mmHg pressure.
(0) Calculate the percentage purity of the sample (NaHCO3)
(Ans: Percentage purity of NaHCO3 = 84.8%)
(ii) How many moles of water are produced?
(Ans: Moles of water produced = 1.262 * 10-2mol)
(ii) What mass of pure HCl is required to neutralize Na2CO3 produce
in the reaction? (Ans: Mass of pure HCI required = 0.923 g).....plz solve it​
