Q:
What volume will 3.50 mol of Xe gas occupy at STP?
A:
78.4 L
Explanation:
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
