How do I get a 3M NaOH solution by using a 10% NaOH solution?

Solutions

Expert Solution

molarity = W*1000/G.M.Wt* volume in ml

3 = W*1000/40*1000

W = 120g

weight of NaOH = 120g

10% NaOH solution = 120*10/100 = 12g

12g of NaOH disolved in 1000ml of solution to get 3M NaOH

10% NaOH solution means 10g of NaOH present in 100ml of solution
