I have 65 gallons of H2O, 35 gallons of 9% sulfuric acid.
\n" ); document.write( " How much of the sulfuric mix do I have to add to the H2O to get a 0.26% concentration
\n" ); document.write( "--------------
\n" ); document.write( "Equation:
\n" ); document.write( "acid + acid = acid
\n" ); document.write( "0.09x + 0*65 = 0.0026(x+65)
\n" ); document.write( "----
\n" ); document.write( "Multiply thru by 10,000 to get:
\n" ); document.write( "900x = 26x + 26*65
\n" ); document.write( "-----
\n" ); document.write( "874x = 26*65
\n" ); document.write( "x = 1.934 gallons (amt of 9% to add)
\n" ); document.write( "-----------------------
