A new Superfuel mixture is created and is not only better for the environment, but is also half the price of regular gasoline at the pumps. As consumers the public loves this new product. However, oil companies have discovered part of the secret formula. They know that within a 65.0 L canister, it contains 37.82% ethanol. Calculate the volume of ethanol in this Superfuel mixture in the 65.0 L container.
