I have a one gallon container and I need to make up a 2.5% solution of acetic acid in that 1 gallon container.
\n" ); document.write( "How much 99% Acetic Acid in mLs do add, to how much water in mls to make up a 2.5% solution of Acetic Acid?
\n" ); document.write( ":
\n" ); document.write( "convert 1 gal to ml: 1 gal = 3.785 liter, which is 3785 ml
\n" ); document.write( ":
\n" ); document.write( "Let x = amt of 99% acetic acid required to accomplish this
\n" ); document.write( ":
\n" ); document.write( ".99x = .025(3785)
\n" ); document.write( ".99x = 94.625
\n" ); document.write( "x = \"94.625%2F.99\"
\n" ); document.write( "x = 95.58 ml of 99% acid required
\n" ); document.write( "then
\n" ); document.write( "3785 - 95.58 = 3689.42 ml of water
\n" ); document.write( ";
\n" ); document.write( "Confirm this by seeing that the amt of acid is equal in each mixture
\n" ); document.write( ".99(95.58) = .025(3785)
\n" ); document.write( "94.6 = 94.6 \n" ); document.write( "
\n" );
