Chlorine can be prepared in the labroratory by the reaction of magnese dioxide with hydrochloric acid (HCL), as described by the chemical equation

MnO2(s) + 4HCL (aq) --> MnCL2(aq) +2h2O (l) +Cl2(g)

How much MnO2(s) should be added to excess HCl(aq) to obtain 255 mL Cl2(g) at 25 degrees Celsius and 775 torr?
