Answer:
154 grams CO₂
Step-by-step explanation:
To find the mass of CO₂, you need to multiply the mole value by the molar mass of CO₂. The molar mass represents the mass (grams) of CO₂ per every one mole. It is important to arrange the ratio/conversion in a way that allows for the cancellation of units.
Atomic Mass (C): 12.011 g/mol
Atomic Mass (O): 15.999 g/mol
Molar Mass (CO₂): 12.011 g/mol + 2(15.999 g/mol) = 44.009 g/mol
3.5 moles CO₂ 44.009 g
