Algebra.Com's Answer #406122 by colliefan(242) ![]() You can put this solution on YOUR website! This is a percentage problem with a twist. Remember all percentages are a ratio of a partial amount over a whole amount. This problem needs you to calculate the part of the chemical over the whole amount of the solution. The trick is that the ratio is in g/L or grams/liters. The amount of chemical given is in kg or kilograms and so we need to change that to grams.\r \n" ); document.write( "\n" ); document.write( "4 kilograms = 4000 grams since 1 kilogram = 1000 g\r \n" ); document.write( "\n" ); document.write( "4000 g / 200L\r \n" ); document.write( "\n" ); document.write( "Simplify this: \n" ); document.write( "40 g/2 L \n" ); document.write( "20 g/1 L\r \n" ); document.write( "\n" ); document.write( "The problem states that 1% is 10 g/L and our solution is twice this amount because it is 20 g/L so the solution is a 2% solution. \n" ); document.write( " \n" ); document.write( " |
