: A 5-quart solution of sulfuric acid and water is 60% acid.
If a gallon of water is added, what percent of the resulting solution is acid?
:
Let x = per cent when a gallon of water is added
:
Change 1 gallon to 4 quarts
:
The amt of acid remains the same
60(5) = x(5 + 4)
300 = 9x
x = 300/9
x = 331%2F3 per cent
