Answer:

Pressure, P = 67.57 atm

Explanation:

Given the following data;

  • Volume = 0.245 L
  • Number of moles = 0.467 moles
  • Temperature = 159°C
  • Ideal gas constant, R = 0.08206 L·atm/mol·K

Conversion:

We would convert the value of the temperature in Celsius to Kelvin.

T = 273 + °C

T = 273 + 159

T = 432 Kelvin

To find the pressure of the gas, we would use the ideal gas law;

PV = nRT

Where;

  • P is the pressure.
  • V is the volume.
  • n is the number of moles of substance.
  • R is the ideal gas constant.
  • T is the temperature.

Making P the subject of formula, we have;

[tex] P = \frac {nRT}{V} [/tex]

Substituting into the formula, we have;

[tex] P = \frac {0.467*0.08206*432}{0.245} [/tex]

[tex] P = \frac {16.5551}{0.245} [/tex]

Pressure, P = 67.57 atm
