A steel reaction vessel of a bomb calorimeter has a volume of 0.217 L, is charged with oxygen gas to a pressure of 84.8 atm at 21.6oC. Calculate the moles of oxygen in the reaction vessel.

Answer : The number of moles of oxygen in the reaction vessel is, 0.761 mole.

Explanation :

To calculate the number of moles of oxygen gas we are using ideal gas equation as follows:

where,

P = Pressure of gas = 84.8 atm

V = Volume of gas = 0.217 L

n = number of moles  = ?

R = Gas constant =

T = Temperature of gas =

Now put all the given values in above equation, we get:

Therefore, the number of moles of oxygen in the reaction vessel is, 0.761 mole.
