A piece of limestone was added to 1.0dm³ of 0.1mol/dm³ Hydrochloric acid. After the effervescence had stopped, 31.25cm³ of the resulting solution required 250cm3 of 0.05mol/dm³ sodium hydroxide for complete neutralization. Calculate the mass of lime stone

(r.a.m: H=1.0, O=16.0, C=12.0, Na=23.0, Cl=35.5, Ca=40.0)
