Question

A sline water solution contains 50 gram of salt dissolving in 40 gram of water calculate the concentration of the solution in term of mass by mass percentage of solution​

Answer 1

Answer:

125%

Explanation:

mass by mass % = mass of solute/mass of solution  x 100

                           =  50/40  x 100

                          = 125%

mark me as brainliest..

Answer 2

Answer:

Mas  of common salt (solute)=50 g

Mass of water (soluted) =400 g

mass of solution=50+40

=90 g

concentration of solution=  M  mass  of solute/  mass of solution ×100

50/40 ×100=125%

Hence, the concentration of the solution is 125%
