Q:

What volume will 3.50 mol of Xe gas occupy at STP?

A:

78.4 L

Explanation:

Eduard22sly

The volume occupied by 3.5 moles of ammonia gas at standard temperature and pressure (STP) is 78.45 L

Data obtained from the question

  • Number of mole (n) = 3.5 moles
  • Pressure (P) = STP = 1 atm
  • Temperature (T) = STP = 273 K
  • Gas constant (R) = 0.0821 atm.L/Kmol
  • Volume (V) =?

How to determine the volume

The volume of the gas at standard temperature and pressure (STP) can be obtained by using the ideal gas equation as illustrated below:

PV = nRT

1 × V = 3.5 × 0.0821 × 273

V = 78.45 L
