How many milliliters of each solution the chemist use? \n" ); document.write( "---------------- \n" ); document.write( "Acid EQUATION: 0.13x + 0.18(50-x) = 0.16*50 \n" ); document.write( "0.13x + 9 - 0.18x = 8 \n" ); document.write( "-0.05x = -1 \n" ); document.write( "x = 20 ml (amount of 13% solution in the mix) \n" ); document.write( "50- 20 = 30 ml (amount of 18% in the mix) \n" ); document.write( "================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
