A 2.24L cylinder of oxygen at 1 atm and ...

A 2.24L cylinder of oxygen at 1 atm and 273 K is found to develop a leakage. When the leakage was plugged the pressure dropped to 570 mm of Hg. The number of moles of gas that escaped will be :

A

0.025

B

0.05

C

0.075

D

0.09

Text Solution

Verified by Experts

The correct Answer is:
a
(a) `Ppropn,` initial mole ` n_(1)=(PV)/(RT)=0.1 " mole" `
`(P_(1))/(P_(2))=(n_(1))/(n_(2))`
`(1)/(0.75)=(0.1)/(n_(2)) " "implies n_(2)=0.075`
Escape mole =0.025

At 273K temp, and 9 atm pressure, the compressibility fog a gas is 0.9 . The volume of 1 mill-moles of gas at this temperature and pressure is :

Initially bulb "a" contained oxygen gas at 27^(@)C and 950 mm of Hg and bulb "B" contained neon gas at 27^(@)C and 900 mm of Hg. These bulbs are connected by a narrow tube of negligible volume equipped with a stopcock and gases were allowed to mix-up freely. The pressure obtained in the combined system was found to be 910 mm of Hg. If volume of bulb B was measured to be 10 L, then find the volume of oxygen gas present initially in bulb "A" .

The decomposition of azo methane, at certain temperature acccording to the equation (CH_(3))_(2)N_(2)toC_(2)H_(6)+N_(2) is a first order reaction.
