Ответ:
3.54 mol
Explanation:
When at STP (Pressure of 1 atm & T of 273.16 K), one mol of any given gas occupies 22.4 liters.
With the above information in mind we can calculate the number of moles, using the factor 22.4 L/mol:
79.2 L ÷ 22.4 L/mol = 3.54 mol
There are 3.54 moles of the gas present in the container.
