What volume in ml of a 60% acid solution must be added to 100 ml of 30% acid to make 36% solution?

September 30th, 2009 | by admin |

can you please give an extremely detailed solution so i can learn from this? i have a test on monday and i have trouble with this.
thanks so much

let the volume of 60% acid solution = x ml

x(60/100) + 100(30/100) = (100+x)(36/100)

0.6x + 30 = 36 + 0.36x

0.24x = 6

x = 6/0.24

= 600/24

= 25 ml
