Question 456112: You need a 65% alcohol solution. On hand, you have a 360 mL of a 15% alcohol mixture. You also have 95% alcohol mixture. How much of the 95% mixture will you need to add to obtain the desired solution?
You will need
? mL of the 95% solution
to obtain
? mL of the desired 65% solution. Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! 360(.15)+n(.95)=.65(360+n)
54+.95n=234+.65n
.30n=180
n=180/.30=600
You need 600 mL of 95% solution to mix with your 15% alcohol solution..
