How many atoms are contained in 16.80 L of Xe at STP?
1 Answer
The answer is
This problem can be solved either by using the ideal gas law,
If one were to use the ideal gas law, it is important to know that STP means a pressure of 1.00 atm and a temperature of 273.15K. In order to determine the number of atoms, we need to first determine the number of moles
Since 1 mole of any substance has exactly
The second method uses the fact that 1 mole of any ideal gas occupies
And, once again
