He is mixing an 80% acid solution with a 30% acid solution. How much of the 80% acid solution will he use? \n" ); document.write( "-------------------- \n" ); document.write( "80% solution DATA: \n" ); document.write( "Amt = x liters; amount of acid is 0.8x liters \n" ); document.write( "---------------------------------- \n" ); document.write( "30% solution DATA: \n" ); document.write( "Amt = 12-x liters; amt of acid is 0.3(12-x) = 3.6-0.3x liters \n" ); document.write( "---------------------------------- \n" ); document.write( "Misture DATA: \n" ); document.write( "Amt = 12 liters; amt of acid is 0.62*12 = 7.44 liters \n" ); document.write( "--------------------------------------- \n" ); document.write( "EQUATION: \n" ); document.write( "acid + acid = acid \n" ); document.write( "0.8x + 2.6-0.3x = 7.44 \n" ); document.write( "0.5x = 4.84 \n" ); document.write( "x = 9.68 liters of 80% solution in the mixture \n" ); document.write( "================================================= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
