Question
What is the temperature when 2.10 moles of nitrogen gas and it has a pressure of 1.25 atm in a 25L of tank?
- 173K
- 252K
- 181K
- 212K
Hint:
Use the ideal gas equation
The correct answer is: 181K
According to Ideal Gas Equation, PV = nRT
P = 1.25 atm, V = 25L, n = 2.10 and R = 0.082 L atm-1 mol-1
Substituting the values,
1.25 x 25 = 2.10 x 0.082 x T
T = 31.25/0.1722
T = 181.47 K or 181 K
