Question

In a container x g of a gas is placed. After some time some gas is allowed to
escape from container. The pressure of gas becomes half and absolute
temperature becomes 2/3rd The amount of gas escaped is​

Answer 1

Answer:

Let molecular mass of gas be m grams

∴ Initial moles=

M

m

Let P

1

=P∴P

2

=P/2

Let T

1

=T∴T

2

=

3

2

T

Let x grams of gas got escaped

∴ Final moles=

M

m−x

We know, PV=nRT

∴

P

n

2

n

Option C.
