Hello!
1. Homework Statement
Please, take a look at the problem and at my solution. Have I done it correctly and is my logic correct?
How much of a 10 liter 30% acid solution must be replaced with pure acid to obtain 10 liters
of a 50% solution?
3. The Attempt at a Solution [/B]
I need to get 10 liters of final solution that contains 5 liters of acid.
Let X be the volume of 30% solution, and Y the volume of pure acid.
Than:
X + Y = 10
0.3 X + Y = 5 I take 0.3X of 30% solution and add Y of acid to get 5 liters of acid.
Y = 2.857
Thank you!
