Please i need help :(

I’m so sry I’ll see if my sister knows how to do it

  The  volume  occupied  by  0.118mol  of He  gas  at  a pressure of  1.05 atm  and  temperature  of  322k  is  calculated   by  use  of   ideal  gas    equation

that  is  PV = nRT
P(Pressure)1.05 atm
v(volume)=?
n  (number  of  moles)=0.118 mol
T(temperature)= 322K

from  equation  above volume(v)= nRT/p

volume(v) =  (0.118 mol  x  0.0821 L.atm/k.mol x322k)  / 1.05 atm =  2.97  L
