Question

What is the number of moles of 6 L of `CO_2`?

Answer 1

That depends on the temperature and pressure... Is this gas at STP or SATP?

Explanation:

You will need to use `PV=nRT` to solve this. If you rearrange to solve for "n", you get:

`n=(PV)/(RT)`

So you need to have temperature and pressure to be able to solve the problem.
