Suppose that you start with 40.00 mL of HX and 10.00 mL of X-. The molarity of HX is initially 0.100 M and the molarity of X- is 0.200 M. These two solutions will be added together into a beaker to create one solution. Adding them together cause them to dilute each other. Calculated the new molarity of HX. Give your answer to four decimal places.
