The pressure inside the television tube containing 2×10¯⁵ g of N₂ at 22 °C is 4.94×10¯⁶ atm

How to determine the mole of fluorine gas

  • Mass of N₂ = 2×10¯⁵ g
  • Molar mass of N₂ = 2 × 14 = 28 g/mol
  • Mole of N₂ =?

Mole = mass / molar mass

Mole of N₂ =  2×10¯⁵ / 28

Mole of N₂ = 7.14×10¯⁷ mole

How to determine the pressure

  • Volume (V) = 3.5 L
  • Temperature (T) = 22 °C = 22 + 273 = 295 K
  • Gas constant (R) = 0.0821 atm.L/Kmol
  • Number of mole (n) =  7.14×10¯⁷ mole
  • Pressure (P) = ?

The pressure inside the television tube can be obtained by using the ideal gas equation as follow:

PV = nRT

Divide both side by V

P = nRT / V

P = (7.14×10¯⁷ × 0.0821 × 295) / 3.5

P = 4.94×10¯⁶ atm
