Question

a solution contains 40 g of common salt in 320 g of water Calcutae the concentration in terms of mass by mass percentage of the solution ​

Answer 1

Explanation:

40/320*100=11.11

thank me later.

Answer 2

SOLUTION :-

Mass of solute (salt) = 40 g

Mass of solvent (water) = 320 g

We know,

Mass of solution = Mass of solute + Mass of solvent

=40 g + 320 g

=360 g

Mass percentage of solution

= Mass of solute / Mass of solution x 100

= 40/360 x 100

Answer = 11.1 %
