Answer:
0.51 moles of gas
Explanation:
Given data:
Pressure of gas = 50.65 kpa (50.65 /101 = 0.5 atm)
Volume of gas = 25 L
Temperature of gas = 300 K
Number of moles of gas = ?
Solution:
The given problem will be solve through ideal gas equation,
PV = nRT
P = pressure
V = volume
n = number of moles
R = general gas constant
T = temperature
Now we will put the values.
0.5 atm × 25 L = n × 0.0821 atm.L /mol.K × 300 K
12.5 atm. L = n × 24.63 atm.L /mol
n = 12.5 atm. L /24.63 atm.L /mol
n = 0.51 mol
