Answer:

58.53 L

Explanation:

Ideal gas equation is

PV = nRT

P - the pressure of the gas = 104.5  KPa

V- the volume occupied by the gas

n  - the number of moles of gas =2.50

R - the universal gas constant, usually given as  0.0821 atm.L/(mol K)

T - the absolute temperature of the gas.= 298K

[tex]V =\frac{nRT}{P}[/tex]

Now substituting vales we get

[tex]V = \frac{2.5\times0.0821\times298}{104.5\times1000}[/tex]

V = 58.53 L
