Answer:

12.387 moles

Explanation:

We are given;

Temperature of chlorine, T = 120°C

But, K = °C + 273.15

Therefore, T = 393.15 K

Pressure, P = 33.3 Atm

Volume, V = 12 L

We are required to calculate the number of moles of chlorine gas,

To find the number of moles we are going to use the ideal gas equation;

PV = nRT

R is the ideal gas constant, 0.082057 L.atm/mol.K

Therefore, rearranging the formula;

n = PV÷RT

Hence;

n = (33.3 atm × 12 L) ÷ (0.082057 × 393.15 K)

  = 12.387 moles

Therefore, the number of moles of chlorine are 12.387 moles

The vessel contains 12.464 moles of chlorine gas.

To calculate the space occupied, we calculate the number of moles.

By ideal gas equation:

PV = nRT

P = pressure = 33.3 atm

V = volume = 12 L

n = moles

R = constant = 0.0816 l/atm/mol.K

T = temperature (K) = [tex]\rm 120^0\;C[/tex] = [tex]\rm 120^0\;C[/tex] + 273 = 393 K

n = [tex]\rm \frac{PV}{RT}[/tex]

n = [tex]\rm \frac{33.3\;\times\;12}{0.0816\;\times\;393}[/tex]

n = 12.464 moles

The vessel contains 12.464 moles of chlorine gas.
