Mix a solution that is 50% acid with a solution that is 100% water to make 4L of a solution that is 10% acid. How much of each solution do you use?
\n" ); document.write( "----------
\n" ); document.write( "Just keep track of the acid.
\n" ); document.write( "------------
\n" ); document.write( "50% solution DATA:
\n" ); document.write( "Amount = x liters ; amt of acid = (1/2)x liters
\n" ); document.write( "---------------
\n" ); document.write( "100% water DATA:
\n" ); document.write( "Amount = \"4-x\" liters ; amt of acid = 0
\n" ); document.write( "---------------
\n" ); document.write( "10% solution DATA:
\n" ); document.write( "Amount = 4 liters ; amt of acid = 0.40 liters
\n" ); document.write( "----------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "acid + acid = acid
\n" ); document.write( "(1/2)x + 0 = 0.40
\n" ); document.write( "x = 0.8 liters
\n" ); document.write( "========================
