You can put this solution on YOUR website!
\"ounce\"?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "ASSUMING this is for weight or \"mass\", then the amount of solution wanted is 8*3=24 \"ounces\". If you want volumes, then you must use the densities of water and the 24% citric acid.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "From a handbook:
\n" ); document.write( "24%___________~1.0972, sp.gr., nearly same as density g/ml.
\n" ); document.write( "10%___________1.0392\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "1 fluid ounce = 29.5735 ml.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Actually, IF IF IF IF you have the percents as w/v, then the solution is simpler than needing account using densities.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let x = volume of the 24% W/V Citric Acid, and you want 24 FLUID OUNCES ( not \"ounces\") of 10% W/V, and y = volume of water to add, then your equations are:
\n" ); document.write( " $\"highlight_green%28%2824x%29%2F24=10%29\"$ and $\"highlight_green%28x%2By=24%29\"$ .
\n" ); document.write( "The solution of the problem is $\"highlight%28x=2.4%29\"$ FLUID OUNCES of 24% citric acid and $\"highlight%28y=21.6%29\"$ fluid ounces water. \n" ); document.write( "
