The subsequent data were taken in measuring the molecular weight of a certain gas by the Regnault Method
Wt. of evacuated bulb = 42. 5050 grams
Wt. of bulb + gas = 43.3412 grams
Wt. of bulb + water = 365.31 grams
Temperature = 25C
Pressure (corrected) = 745 mm Hg
Find the molecular weight of the gas.
