The number of mole of air present is 0.056 mole

Data obtained from the question

  • Volume = 1.35 L
  • Pressure (P) = 750 torr
  • Temperature (T) = 17 °C = 17 + 273 = 290 K
  • Gas constant (R) = 62.396 L•torr/mol•K
  • Number of mole (n) = ?

How to determine the number of mole

The number of mole present can be obtained by using the ideal gas equation as illustrated below:

PV = nRT

Divide both side by RT

n = PV / RT

n = (750 × 1.35) / (62.396 × 290)

n = 0.056 mole
