Average Titre: 28.73dmol-3 using a mass of 2.654g of Na2CO3

Na2CO3 + H2SO4 → CO2 + H2 One mole of Na2CO3 reacts with one mole of H2SO4 therefore.

Na2CO3 = 106g 1 mole = 106g 0.1 moles = 10.6g

2.65g of solid mass in 25cm3 10.6g of solid mass in 100cm3

Number of moles = Mass ÷ RMM

2.65 ÷ 106= 0.02

Number of moles ÷ volume in dm3

0.02 ÷ 0.025 = 0.8

The concentration of Na2CO3 is 0.08mol

0.08 x 0.025 0.028

0.071mol of H2SO4
