A chemist wants to make 44 mL of a 16% acid solution by mixing a 10% acid solution and an 18% acid solution. How many milliliters of each solution should the chemist use? \n" ); document.write( "----- \n" ); document.write( "Equation: \n" ); document.write( "acid + acid = acid \n" ); document.write( "0.10x + 0.18(44-x) = 0.16*44 \n" ); document.write( "----- \n" ); document.write( "10x + 18*44 - 18x = 16*44 \n" ); document.write( "-8x = -2*44 \n" ); document.write( "x = 11 mL (amt. of 10% solution needed) \n" ); document.write( "44-x = 33 mL (amt. of 18% solution needed) \n" ); document.write( "=================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "===================== \n" ); document.write( " |
