You have a beaker containing 20.00 ± 0.04 mL of a solution of HCl. The molarity of the solution is (10.05 ± 0.03)·10^-2 mol·L^-1. It should be quite easy to calculate that this beaker contains 2.0100 mmol HCl. What is the absolute error in this amount of mmol, given the errors in volume and molarity of the solution? Note: use a dot (.) for decimals, not a comma (,)!
