The number of mole of the gas present in the room given the data is 0.069 mole

Data obtained from the question

  • Volume (V) = 165 m³
  • Temperature (T) = 20 °C = 20 + 273 = 293 K
  • Pressure (P) = 1 atm
  • Gas constant (R) = 8.21 m³.L/Kmol
  • Number of mole (n) =?

How to determine the number of mole

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

PV = nRT

n = PV / RT

n = (1 × 165) / ( 8.21 × 293)

n = 0.069 mole

Answer:

6859 moles

Explanation:

n=(PV)/RT=(100000*165)/(8.21*293 Kelvin)=6859 moles

20 deg Celsius is 293 Kelvin
