Answer:
Explanation:
Given parameters:
Number of moles = 12moles
Temperature = 273K
Pressure = 75kPa, convert to atm:
1kPa = 0.00986923atm
75kPa = 75 x 0.00986923 = 0.74atm
Unknown:
Volume of the oxygen gas
Solution:
We simply apply the idea gas law which is :
PV = nRT
Since the unknown is volume, we make it the subject of the formula:
V = [tex]\frac{nRT}{P}[/tex]
R is the gas constant and its value is given as 0.082
V = [tex]\frac{12 x 0.082 x 273 }{0.74}[/tex] = 363.01L
