**Reiny**, Monday, July 21, 2008 at 12:25pmSomething usually stays the same, in your case it would be the amount of antiseptic which would be 25% of 32 g or 8 g.

So let's add x g of distilled water, so now we have (32+x) g.

10% of that is still 8 g of the antiseptic.

so equation : 10/100(x+32) = 8

solve that to get x = 48 g
