Question

A solution containd 50g of salt in 360g of water. Calculate the concentration in the term of mass by mass percentage of solutions

Answer 1

C% = Msolute/Msolution * 100
Let 
Msolute= 50g
Msolvent = 360g
Msolution= Msolute + Msolvent 
50+ 360=410g
Apply formula 
C% = 50 / 410 * 100 = 12.1%
Therefore the concentration percentage is 12.1%

Answer 2

we are given solute that is salt 50 gram and
solvent that is 360 gram water we will add both solute and solvent to find the solution that will be 410 grams then the formula of mass by mass percentage mass of solute open mass of solution in 200 that is 50 into 410 into 100
50/410*100 =12.2
