A chemist has 60 g of a solution that is 70% acid. How much water should be added to make a solution that is 40% acid?
\n" ); document.write( "----------------
\n" ); document.write( "The original solution has 42 gm (60*0.7) of acid, 18 gm of water.
\n" ); document.write( "Adding water to make 42 gm 40% means 100% will be 42/0.4 grams, = 105 grams total.
\n" ); document.write( "He'll have to add 45 grams of water.
\n" ); document.write( "You'd think a chemist could figure that out himself.
\n" ); document.write( "
