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.
The resulting solution has an osmotic pressure of 0.544 atm at 25°C. Assuming that the organic compound is a nonelectrolyte, what is its molar mass?
