What is neutralization?
The term neutralization refers to the reaction between an acid and a base that yileds salt and water only.
The equation of this reaction is; 2HCl + CaCO3 ----->CaCl2 + CO2 + H2O
Number of moles of CaCO3 = 0.350 g/100 g = 0.0035 moles
Since 2 moles of acid reacts with 1 mole of CaCO3
x moles acid reacts with 0.0035 moles of CaCO3
x = 0.007 moles
Mass of acid = 0.007 moles * 36 g/mol = 0.252 g
