Question

A student Collects 100 ml of nitrogen gas at 380mm HG and a temperature of 27C. What will be the volume of gas at 127C and 1 atm​

Answer 1

As we know 1atm=760mm of Hg

380mm=380/760 atm

use law gaseous equation

1)Case( I)

pv=nrt

380/760×100=nR×300

from here n=

380/228R

2)Case(2)

1×v=380/228R ×400. ( moles will remain constant)

So

V=380×400/228R

V=41.7(approx)

have a nice day
