Hai,
First of all the question hasn't mentioned whether it is in standard temperature and pressure.
So we just assume the temperature and pressure remains constant .
Therefore we use the equation of
PV=nRT........ (1)
(the ideal gas equation)
From it we get the equation of
V1/V2=n1/n2.... ...... (2)
On substituting the values
2.5/V2=0.5/0.55
V2=2.75
I hope the answer is clear to you..

Greeting,
Very simple volume and no. of moles are directly proportional i.e. applying Avagadro's law i.e. V1/n1=V2/n2
Where V1=0.5 L, V2=?, n1=0.5 moles, n2=0.55 moles
There by applying avagadro's law:
0.5 L/0.5 moles=V2/0.55 moles
V2=0.55 L is the answer
