Question

A solution contains 50 grams of salt in 350 grams of water. Calculate the concentration of the solution and give reason for your method.

Answer 1

Answer:

0.125%

Explanation:

mass of solute = 50 grams

mass of solvent = 350 grams

mass of the solution = mass of solute+mass of solvent

= 50+350

400 grams ...

now......

concentration of the solution is =

$\frac{mass \: of \: solute}{mass \: of \: solution}$

$\frac{50}{400}$

0.125%
