Answer:

0.324 mole of sodium

Explanation:

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

Therefore,

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.
