Answer:   0.75 mol

Explanation:

- For any type of gas, the molar volume (the volume of one mole of     substance) at Standard Temperature and normal Pressure  is 22.4 L.

- Using cross multiplication,   1 mol    →   22.4 L

                                                        ?       →   16.8 L

So number of moles of N2 in 16.8 L  =  ( 16.8 L × 1 mol ) / 22.4 L = 0.75 mol ..

The number of mole of nitrogen gas in the 16.8 L container is 0.75 mole

Data obtained from the question

  • Volume (V) = 16.8 L
  • Pressure (P) = STP = 1 atm
  • Temperature (T) = STP = 273 K
  • Gas constant (R) = 0.0821 atm.L/Kmol
  • Number of mole (n) =?

How to determine the number of mole

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

PV = nRT

Divide both side by RT

n = PV / RT

n = (1 × 16.8) / (0.0821 × 273)

n = 0.75 mole

Thus, the number of mole of the gas present is 0.75 mole
