A quantity of an ideal gas is collected in a graduated tube over the mercury in a barometer type arrangement. The volume of gas at 20ºC is 50 ml and the level of mercury is 100 mm above the outside of the mercury level. The atmospheric pressure is 750 mm. Volume of gas at STP is : (Take R = 0.083 lt. atm/K/mole)
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(40.3 Ml)
The number of moles of the gas = 
= 0.0018 mol.
Hence volume at STP = 22400 × .0018 = 40.3mL
