Question

Volume of solute
X100
Volume of solution
ample 2.1 A solution contains 40 g of
common salt in 320 g of water
Caleulate the concentration in terms of
mass by mass percentage of the
solution
tution:​

Answer 1

Answer:

Mas of common salt (solute)=40 g

Mass of water (soluted) =320 g

mass of solution=320+40

=360 g

concentration of solution=
