Answer:
25 grams of sodium sulphate is required..
Explanation:
MASS OF SOLUTION =MASS OF SOLUTE + MASS OF SOLVENT
GIVEN THAT THE MASS PERCENT OF SODIUM SULPHATE IS 20%..
LET THE MASS OF SODIUM SULPHATE WHICH IS REQUIRED TO PREPARE THIS SOLUTION BE "X" GRAMS.
GIVEN THAT THE MASS OF WATER IS 100 GRAMS
SO,
20={X/(X+100)}*100
20/100={X/X+100}
1/5=X/X+100
X+100/5=X
X+100=5X
5X-X=100
4X=100
X=100/4
X=25....
HOPE U GOT IT CLEARLY
THANK U ...
