From the question given above, the following data were obtained:
Volume of sodium = 7.25 L
Number of mole of sodium =..?
The number of mole of sodium that occupies 7.25 L can be obtained as follow:
22.4 L = 1 mole

7.25 L = 7.25 L × 1 mole / 22.4 L
7.25 L = 0.324 mole
Therefore, 0.324 mole of sodium is present in the container.
Answer:
Compound
Explanation:
We want to know if it's a compound or a mixture.
An example of a mixture is salt water: you can heat it hot enough to boil off the water, leaving only the salt. This is a physical change, which is how you know it's a mixture.
Something like gold is a compound: if you heat it, or hit it, you'll still only have gold. You can only break it down by chemical means, which is how you know it's a compound.
