Na2CO3 + 2HCL ==> 2NaCl + CO2 + H2O.
mols HCl = M x L = 0.8 x 0.025 = 0.02
mols Na2CO3 must 1/2 that = 0.01
grams Na2CO3 = mols x molar mass = 0.01 x 106 = 1.06
1.06 g/20 mL = ?g/L
20cm^3 of sodium carbonate solution was reacted completely with 25cm^3 of 0.8 M HCL according to the equation. Na2CO3+2HCL-2NaCl+CO2+H2O.Calculate the concentration of the Na2CO3 in grams per litre
