Question

Calculate the amount of salt required to prepare 250 g of 5% solution of salt in water.

Answer 1

Explanation:

given mass of solution = 250g

mass percent = 5%

We know that

MASS PERCENT= mass of solute/mass of solution × 100

let the mass of solute be x

so

that is equal to

5= x / 250 × 100

now,

5×250/100 = x

1250/100 = x

so, x=12.50

so , here 12.50% of salt is in water

given 250g of solution, so water is equal to 250-12.50 = 237.5g

Answer 2

Answer:

237.5 is a answer I hope it helps you
