common salt in 320 g of water.
Calculate the concentration in terms of
mass by mass percentage of the
solution.
lution:​

Answer 1

Explanation:

solute= 40g

solvent = 320 g

solution = 320 + 40 = 360 grams

concentration percent = (mass of solute / mass of solution ) × 100

= 40 /360 × 100

= 11.1111111111.........%

= 11.11 %
