Question

when 400 gram of a solution was cooled 50 gram of solute was formed what is the percentage of remaining solution ​

Answer 1

Answer:

Step-by-step explanation:

⇒Weight of solution=400 g,

⇒Weight of solute is 20×400/100=80 g,

⇒Weight of solute precipitated is 50 g,

⇒Weight of solution remained in solution 80-50 is 30 g,

⇒Weight of solution remained 400-50 is 350 g,

⇒Hence % by weight is is 30/350×100 is 8.57%.
