Water is a 0% acid solution.
\n" ); document.write( "Let x be the ml of water added.
\n" ); document.write( "\"0%28x%29%2B30%2810%29=15%2810%2Bx%29\"
\n" ); document.write( "\"150%2B15x=300\"
\n" ); document.write( "\"15x=150\"
\n" ); document.write( "\"highlight%28x=10%29\"
\n" ); document.write( "10 ml of water will double the volume and halve the concentration.
