Answer:

Number of moles, n = 68.20 moles

Explanation:

Given the following data;

  • Volume, V = 2200 m³
  • Temperature, T = 388 K
  • Pressure, P = 100 kPa
  • Ideal gas constant, R = 8.314 J/mol·K  or 0.08206 L·atm·mol−1·K−1

To find the number of moles, we would use the ideal gas law equation;

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 n the subject of formula, we have;

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

Substituting into the formula, we have;

[tex] n = \frac {100 * 2200}{8.314 * 388} [/tex]

[tex] n = \frac {220000}{3225.832} [/tex]

Number of moles, n = 68.20 moles
