  1. 110g of salt is present in 550g of solution. Calculate the concentration of solution.

Dear Student,
Mass of solution = 550 gm
Mass of solute = 110 gm

Concentration of a solution = Mass of soluteMass of solution×100  = (110/550) x 100 = 20 % W/w (that is mass by mass percentage)

Hello!! Hope this helps!!

The concentration of salt is determined by the division of mass of the solute by the mass of the solution and the percentage is obtained by multiplying the value by 100.

The quotient of the division of 110 by 550 is 0.2 here.

So after multiplying it with 100, it is 20%. So the concentration is 20%.
