A quantity of gas is collected in a graduated tube over the mercury. The volume of gas at 18 ºC is 50 ml and the level of mercury in the tube is 100 mm above the outside mercury level. The barometer reads 750 torr. Hence, volume at S.T.P. is approximately :
Text Solution
Verified by ExpertsThe correct answer is:
B
Net pressure of gas = P gas
P gas (P xSl ) = 650 mm.
= 
= 
V 2 = 40.11 ml P 1 = 9 atm P 2 = 6 atm
V 1 = 5 Lt. V 2 = 10 Lt.
