Question

The density of 10% by mass of Kcl solution is 1.06 g/cm3 calculate the molarity of solution

Answer 1

Answer:

Density =mass /volume

1.06g/cm^3=100g/volume

Volume=100/1.06 cm^3

=904.3 cm^3

=904.3ml

No. Of moles of KCl in solution

=10/904.3

=100/9043 =0.011 moles

Molarity=0.011/0.9043= 1.42M
