Answer:
Given :-
- Moles = 2.10
- Gas = Nitrogen
- Pressure = 1.25 atm
- Volume = 25 l
To Find :-
Temperature
Solution :-
As we know that
PV = nRT
Here,
P = Pressure
V = Volume
n = Moles
T = Temperature
1.25 × 25 = 2.1 × 0.082 × T
31.25 = 2.1 × 0.082 × T
31.25 = 1.722T
31.25/0.1722 = T
181 ≈ T
Temperature is 181 K

Given: Mole = 2.10
Pressure = 1.25 atm
Volume = 25L
R = 0.082 L atm⁻¹mole⁻¹
To find: Temperature
Solution: According to the ideal gas law,
PV = nRT
Where P = pressure, V = volume of the gas, n = number of moles, R = universal gas constant, T is the temperature of the gas.
1.24 × 25 = 2.10 × 0.082 × T
T = 1.24×25/0.082
= 43K or -230 °C
Therefore, the temperature of the 2.10 moles of Nitrogen gas having a pressure of 1.25 atm and in a tank of 25L is 43K.
- The ideal gas equation is the gas equation of a hypothetical gas that obeys all the hypotheses of the gas.
- The ideal gas equation gives the effect of pressure and temperature on the volume of a gas is called the ideal gas equation.
- It is also known as combined gas law.
- PV = nRT is the equation of ideal gas law.
