Answer:

How much pure alcohol must be added to 400 mL of a 15% solution to make its strength 32%.

Answer 2

Answer:

By the method of alligation

we have to add 100% alcohol to make it 32% strength in the mixture of 15% alcohol

15%. 100%

32%

100 - 32. 32 - 15

68 : 17

4 : 1

therefore therefore if 4 equal to 600ml then one equal to 150 ml

So we have to add 150 ml alcohol.
