Question 68196
An 800 g solution of acid and water contains 128 g of acid.  What percent of the solution is acid?

x=percent of the solution that is acid

800x=128 divide both sides by 800


x=0.16 or 16%------------------------------is acid

CK
800-128=672 g of water

672/800=.84 or 84% water

84%+16%=100%


Hope this helps---ptaylor
