Question

For reactions occurring at STP, the conversion between moles and liters is 22.4 L = 1 mol for all gases. How many moles of sodium are in a 7.25-liter container at STP?

0.213 mol

0.126 mol

3.23 mol

0.324 mol

Answer 1

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.
