Question

if 53 gram of Na 2 CO 3 is dissolved in 500 ml solution find molarity of N A 2 CO 3​

Answer 1

Answer:

Explanation:

Given mass of Na2Co3 = 53 g

Volume of solution given = 500 ml

1 l =1000 ml

x l = 500 ml

x l = 500/1000

Volume in l =0.5l

Molarity = moles of solute / volume of

solution in litre

Mole of solute = given mass / molar

mass

Moles of solute = 53/106

=0.5 moles

Molarity = 0.5 moles /0.5 l solution

Molarity = 1 M
