Answer:
About 0.08486 moles
Explanation:
PV=nRT, when P is the pressure in atmospheres, V is the volume in liters, n is the number of moles, R is the universal gas constant, and T is the temperature in Kelvin.
[tex]0.432 \cdot 5= n \cdot 0.0821 \cdot 310[/tex]
[tex]n\approx 0.08486[/tex] moles
Hope this helps!
