10 moles of a active radio isotope M g are disintegrating at 300 K in a cylinder enclosed with a frictionless piston as given below A 12 4M g 2N g a particles Z 6 The half life of the radioactive sample is 69 3 hours The a particles emitted forms He g by trapping electrons in the cylinder As He g forms piston moves up against constant external pressure of 1 atm The work done by the gas in cal by the end of initial one hour is assume rate remains almost constant during this period Given R 2 Cal mol K In 2 0 693 Report your answer by dividing it by 30
