The ideal gas law relates the amount of gas present to its pressure, volume, and temperature. The ideal gas law is typically written as
đđ=đđ đ
Â
where đ is the pressure, đ is the volume, đ is the number of moles of gas, đ  is the ideal gas constant, and đ is the temperature.
Rearrange the equation to solve for đ.
What is the pressure of 0.293 moles of an ideal gas at a temperature of 298.0 K and a volume of 4.62 L?Â
Solution:
The ideal gas equation can be used:
PV = nRT
Rearrange the equation to solve for P:
P = nRT / V
Plug in the numbers:
P = (0.293 mol Ă 0.0821 atm L molâ1 Kâ1 Ă 298.0 K) / (4.62 L) = 1.55 atm
P = 1.55 atm
Answer: The pressure of gas is 1.55 atm
