To solve this problem, we can use the ideal gas law equation:
PV = nRT
Where:
P = pressure in atm
V = volume in liters
n = number of moles
R = ideal gas constant (0.0821 L atm/ mol K)
T = temperature in Kelvin
We can rearrange the equation to solve for the number of moles:
n = PV / RT
Substituting the given values:
P = 0.36 atm
V = 4.20 L
R = 0.0821 L atm/ mol K
T = 310 K
n = (0.36 atm x 4.20 L) / (0.0821 L atm/ mol K x 310 K)
n ≈ 0.017 moles
Therefore, the correct answer is c) 0.004 moles.
How many moles of gas are in a 4.20 L container at 310 K and 0.36 atm? Given R= 0.0821 L atm/ mol K.
