What volume, in ml, of a 60% of HCl acid solution must be added to 100 ml of a 30% HCl solution to make a 36% HCl solution.
We need 2 alegabreic (?) equations.
The first I can get is:
0.36x - 0.60y = 100ml (this is probably wrong)?
Blah. I can't get the other one. -.-
VolHCL*.60 + 100ml*.30 = (VolHCL +100ml).36
I don't see that you need a second.
