You can put this solution on YOUR website! A Chemist has 100g of 25% acid solution. How much of these solution he needs to drain and replaced with 70% acid solution to obtain 100g of 60% acid solution
let x=amt of 25% solution to drain and replace with 70% solution
25%
25%(100-x)+70%x=60%100
25-.25x+.70x=60
.50x=35
x=70
How much of these solution he needs to drain and replaced with 70% acid solution to obtain 100g of 60% acid solution? 70 mg
