Answer: The volume occupied by He is 62.4 L

Explanation:

According to ideal gas equation:

[tex]PV=nRT[/tex]

P = pressure of gas = 0.980 atm

V = Volume of gas = ?

n = number of moles = 2.50 mol

R = gas constant =

T =temperature =[tex]25.0^0C=(25.0+273)K=298.0K[/tex]

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

[tex]V=\frac{2.50mol\times 0.0821 Latm/K mol\times 298.0K}{0.980atm}=62.4L[/tex]

Thus the volume occupied by He is 62.4 L
