a gas with a pressure of 845 torrs occupies 11.0 l what will the pressure be for a volume of 2.50 l if the temperature remains constant
The ideal gas law relates the amount of gas present to its pressure, volume, and temperature. The ideal gas law is typically written as
𝑃𝑉=𝑛𝑅𝑇
where 𝑃 is the pressure, 𝑉 is the volume, 𝑛 is the number of moles of gas, 𝑅 is the ideal gas constant, and 𝑇 is the temperature.
Rearrange the equation to solve for 𝑇.
What is the temperature of 0.597 mol of an ideal gas with a volume of 8.22 L and a pressure of 1.678 atm?
