Answer:

1.33 moles CO2

Step-by-step explanation:

The number you are converting is 58.4 g CO2, so you start with this value. The conversion factor is 44.0 g/mol CO2. In order to cross out the grams, the grams must go on the bottom of the conversion factor.

1 mol CO2
58.4 g CO2 x -------------------------- = 1.33 moles CO2
44.0 grams

The answer has three sig figs.
