Steps for Ideal Gas Law Calculator

Back to Top
Step 1 :  

Ideal Gas Law Formula Formula:

General Gas Equation: PV = nRT
Pressure(P) = nRT / V
Volume(V) = nRT / P
Temperature(T) = PV / nR
Moles of Gas(n) = PV / RT
where,
P = Pressure,
V = Volume,
n = Moles of gas,
T = Temperature,
R = 8.314 J K-1 mol-1, ideal gas constant.



Step 2 :  

State the equation you plan to use and plug in the values.

  1. Find the volume from the 0.361 moles gas at 300kpa and 400K temperature?


    Step 1 :  

    Given that:
    Pressure(P) = 300 kPa,
    Moles of gas(n) = 0.361 moles,
    Temperature(T) = 400K
    Volume(V) = ?



    Step 2 :  

    Substitue the given values in the formula:
    Volume(V) = nRT / P
    V = (0.361 × 8.314 × 400) / 300 [Since R = 8.314 J K-1 mol-1]
    V = 1200.541 / 300
    V = 4.002L



    Answer  :  

    Volume(V) = 4.002L



  2. Find the temperature from the 360ml cylinder contaning 0.60 moles gas at 264kpa?


    Step 1 :  

    Given that:
    Volume(V) = 360ml = 360 / 1000 = 0.36 L,
    Moles of gas(n) = 0.60 mol,
    Pressure(P) = 264 kPa
    Temperature(T) = ?



    Step 2 :  

    Substitue the given values in the formula:
    Temperature(T) = PV / nR
    T = (264 x 0.36) / (0.60 x 8.314)
    T = 95.04 / 4.9884
    T = 19.052 K



    Answer  :  

    Temperature(T) = 19.052 K
