Algebra.Com's Answer #646572 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! In a chemistry class, 8 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( "Quantity Eq:: 8 + t = s \n" ); document.write( "Iodide Eq:: 0.32 + 0.10t = 0.06s \n" ); document.write( "----------------------------------------- \n" ); document.write( "Substitute for \"s\" and solve for \"t\":: \n" ); document.write( "0.32 + 0.10t = 0.06(8 + t) \n" ); document.write( "32 + 10t = 48 + 6t \n" ); document.write( "4t = 16 \n" ); document.write( "t = 4 liters (amt. of 10% solution needed) \n" ); document.write( "----- \n" ); document.write( "Ans: B \n" ); document.write( "----- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "----------- \n" ); document.write( " \n" ); document.write( "A) 5.0 L \n" ); document.write( "B) 4.0 L \n" ); document.write( "C) 8.0 L \n" ); document.write( "D) 3.0 L \n" ); document.write( " |
