Answer:

58.53 L

Step-by-step 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


V =(nRT)/(P)

Now substituting vales we get


V = (2.5*0.0821*298)/(104.5*1000)

V = 58.53 L
