  • Volume=25L
  • Temperature=5°C
  • Pressure=89.9kPa

Now

[tex]\\ \rm\rightarrowtail PV=nRT[/tex]

[tex]\\ \rm\rightarrowtail n=\dfrac{PV}{RT}[/tex]

[tex]\\ \rm\rightarrowtail n=\dfrac{89.9(25)}{5R}[/tex]

[tex]\\ \rm\rightarrowtail n=89.9(5)/R[/tex]

[tex]\\ \rm\rightarrowtail n=449.5/R mol[/tex]
