Question

400 gram of solution having 20% weight by weight solute is cooled than 50 gram of solute precipitated then find out the percent weight by weight of solute in the remains solution​

Answer 1

Answer:

Weight of solution = 400g Weight of solute = 20 × 400100 = 80 g Weight of solute precipitated = 50g Weight of solute remained in solution = 80

Answer 2

Answer:

initial solute =20/100×400=80g

precipitated=50g

hence, left in solution

=80-50=30g
