2 solutions of h2so4. one is 40% concentration and one is 25% concentration. how much of each do I need to get 137 liters of 36% solution?
\n" ); document.write( "------------------------
\n" ); document.write( "acid + acid = acid
\n" ); document.write( "0.40x + 0.25(137-x) = 0.36*137
\n" ); document.write( "Multiply thru by 100 to get:
\n" ); document.write( "40x + 25*137 - 25x = 36*137
\n" ); document.write( "15x = 11*137
\n" ); document.write( "x = 100.47 liters (amt. of 40% solution needed in the mixture)
\n" ); document.write( "137-100.47 = 36.53 liters (amt of 25% solution in the mixture)
\n" ); document.write( "============================================================
