Question #a967c

Answer 1

`4.4 g` of `CO_2` at STP has a volume of 2.2 L.

Explanation:

First, you start off with your given `4.4 g` of `CO_2`. You convert it into moles using the Periodic Table. This may vary according to the atomic mass numbers on your Periodic Table.

On my version of the Periodic Table, 1 mol of Carbon has a mass of `12.0111 g` and 1 mol of Oxygen has a mass of 15.9994 grams.

So 1 mol of `CO_2` is `12.0111 * (15.9994 * 2) = 44.0099 g`.

`4.4 /44.0099` gives you `0.10 mol` (2 significant figures).

1 mol of any gas will be equal to 22.4 L at STP. So `0.10` `mol` `CO_2` `*` `22.4 L = 2.2 L` of `CO_2` at STP. (2 significant figures)
