Final answer:
There are approximately 0.446 moles of fluorine gas in 10 liters.
Step-by-step explanation:
In order to determine the number of moles of a gas, you need to know the volume of the gas and its molar volume at a given temperature and pressure. The molar volume of a gas at standard conditions (0 degrees Celsius and 1 atmosphere pressure) is 22.4 liters.
Since you have 10 liters of fluorine gas, you can calculate the number of moles by dividing the volume by the molar volume:
Number of moles of fluorine gas = Volume of gas / Molar volume = 10 L / 22.4 L/mol = 0.446 moles
Therefore, there are approximately 0.446 moles of fluorine gas in 10 liters.
