Question

5.8 gm of NaCl is added in 100 ml of water to prepare a solution. Find out
the molarity & Normality of solution.​

Answer 1

Molarity =moles /litre

moles=mass/molar mass

=5.8/58

=0.1moles

Molarity= 0.1/0.1 1litre=1000ml

= 1molar (approx.)

Normality= molarity x n (n=charge of anion or cation

of any salt)

1 x 1=1 normal
