Which of the following is NOT true about helium gas and argon gas samples at the same temperature and pressure?
Question 1 options:
|
If you have twice as many moles of argon as helium, the volume of argon will be twice as large. |
|
|
The same number of moles of each will occupy the same volume. |
|
|
One mole each of helium and argon in a container will take up twice the volume of 1 mole of helium by itself. |
|
|
The same number of grams of each will occupy the same volume. |
|
|
4.00 grams of helium will occupy the same volume as 39.95 grams of argon. |
Homework Answers
Ans : The same number of grams of each will occupy the same volume
The same number of grams of both the gases will not occupy the same volume. This is because the helium gas is lighter in mass than the argon gas and since the number of moles of lighter gas will be more than the heavier gas for the same amount of grams , the volume of lighter gas will be more.
