Question #5db68

Answer 1

The formula is `CO_2` and the mass is 673.9 g.

Explanation:

`6.02xx10^(23)` particles of substance is known as a mole of that substance. This number is known as Avogadro's constant.

So, if we divide the given amount by `6.02xx10^(23)`, we have the number of moles of carbon dioxide, `CO_2`.

`9.22xx10^(24)-:6.02xx10^(23)=15.316` moles

The mass of one mole of `CO_2` is 44.0 g (based on the atomic masses of carbon (12) and oxygen (16)).

`15.316 "mol" xx 44.0 g/"mol" = 673.9 g`
