Question

5.3 of na2co3 present in500ml solution find the molarity of solution​

Answer 1

Answer:

5.3 5000present solution molarlity

Answer 2

Molecular mass of na2co3 = 106g/mol

Number of moles = 53/106 = 0.05mol

As 0.05 mol are dissolved in 500 ml

Number of moles dissolved in 1000 ml or molarity of the solution

= 0.05/500 = 1000 = 0.1 M
