c.) 22.4 L/1 mole
Explanation:
Using the general gas law equation as follows:
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
The standard values for a gas are as follows:
Standard pressure of a gas = 1 atm
Standard temperature of a gas = 273K
According to the information in the question, n = 12.3 moles
Using PV = nRT
V = nRT/P
V = 12.3 × 0.0821 × 273/1
V = 275.68 L
Based on this value of volume in liters for 12.3moles of Br gas, the volume per mole at standard temperature and pressure will be 275.68/12.3 = 22.4 Litres per mole. Hence, the answer is 22.4 L/1 mole.
