To dilute 600 ml of 95% alcohol into 75% disinfectant alcohol, how many ml of distilled water should be added?

To dilute 600 ml of 95% alcohol into 75% disinfectant alcohol, how many ml of distilled water should be added?

Let's add x ml
95%*600=75%*（600+X）
570=450+0.75X
0.75X=120
X=160

How to dilute 100 ml 95% alcohol to 75%?
Ask the calculation formula

100*95%=x*75%
x=126.67
So we need to add water 126.67-100 = 26.67 ml
