How many moles are in 28 grams of CO2?

The molecular weight of a material is required to tell an individual how many grams there are in one mole of that chemical substance i.e. molecular weight of any substance contains 1 mole of that substance. Then 28 g of CO2 contains = 0.636 moles of CO2. Hence we can say that there are 0.636 present in 28 g of CO2.
