Question

two vessels A and B having volume 1 litre and 2 litre respectively contain ideal gases if pressure in both vessels are equal while temperature of vessel a is 273 degree Celsius and of vessel b is 546 degree Celsius then ratio of moles of ideal gas in vessels a and b is​

Answer 1

Answer:

Correct option is C)

For ideal gas, PV=RT and M=ρV

thus,

ρ

PM

=RT

here,

ρ

A

A

=RT....(1)

and

ρ

=RT....(2)

(1)/(2)⇒
