4. What is the volume, in liters, of a 3.00 mole sample of carbon dioxide at STP?

One mole of ideal gas occupies 22.4L volume at STP

Explanation:

So., we treat carbon dioxide an ideal gas:

3 mol x 22.4L •Mol-¹≈? ?L

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.
