Algebra.Com's Answer #304493 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! in a chemistry class, 7 liters of a 4% silver iodide solution must be mixed with a 10% solution to get a 6% solution. how many liters of the 10% solution are needed? \n" ); document.write( "--------------------------------- \n" ); document.write( "Equation: \n" ); document.write( "silver + silver = silver \n" ); document.write( "0.04*7 + 0.10x = 0.06(7+x) \n" ); document.write( "------------------------------------ \n" ); document.write( "Multiply thru by 100 to get: \n" ); document.write( "4*7 + 10x = 6*7 + 6x \n" ); document.write( "4x = 2*7 \n" ); document.write( "x = 3.5 liters (amt. of 10% solution needed) \n" ); document.write( "================================================= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
