Question

The concentration of a salt solution in terms of mass percentage is 20% and the mass of the solution is 500g. The mass of the solute present in the solution will be:

point

(a) 200g

(b) 100 g

(c) 300 g

(d) 50g​

Answer 1

Answer:

option (B)

Explanation:

mass by mass percentage of solution = (mass of solute/mass of solution) x 100

Therefore, (mass of solute/mass of solution) = 20/100 = 1/5

hence, mass of solute = mass of solution/5 = 550g/5 = 110 grams

The mass of solute is 110 grams.

Answer 2

Answer: option (b) is a correct answer just use percentage formula 20/10×500/1 and the answer will be 100g that is option (b)
