How many ounces of water should a chemist remove from 20 ounces of a 20% sulfuric acid solution to increase it to a 40% sulfuric acid solution?
\n" ); document.write( "-------
\n" ); document.write( "Equation:
\n" ); document.write( "water - water = water\r
\n" ); document.write( "\n" ); document.write( "0.80*20 - x = 0.60(20-x)
\n" ); document.write( "-----
\n" ); document.write( "Multiply thru by 100 to get:
\n" ); document.write( "80*20 - 100x = 60*20 - 60x
\n" ); document.write( "40x = 20*20
\n" ); document.write( "x = 10 ounces (amt. of water to be removed)
