$QUESTION$
A solution contains 40g of common salt in 320g of water. calculate the concentration in terms of mass by mass percentage of the solution :-​

Answer 1

SOLUTION

Mass of common salt (solute)=40 g

Mass of water (soluted) =320 g

mass of solution=320+40

=360 g

concentration of solution=

$\frac{ \: Mass \: of \: solute \: }{mass \: of \: soutin \: } \times 100$

$\frac{40}{360} \times 100$

$\ = 11.11\%$

: Hence, the concentration of the solution is 11.11%
