Question

5.3 GM's of na2co3 are dissolved in 3 litres of water what is the molarity of the solution.​

Answer 1

0.0167 M

Explanation:

Given: mass of Na₂CO₃ = 5.3, V = 3 L, number of molesc = ?

Number of moles of solute = mass of solute/molecular mass of solute

                                               = 5.3/ 106

                                                = 0.05 moles

We know that,

Molarity = number of moles of solute/ Volume of solution in L

               = 0.05/3

               = 0.0167 M
