Question

How many pounds of CO2 are in 8.65 x 10 to the power of 20 molecules of CO2

Answer 1

1 pound = 453.592 g

1 mole CO2 = 44 g CO2 = 6.02x10^23 molecules CO2 (Avogadro's number)

44 g CO2 ---------- 6.02x10^23 molecules CO2

X ---------- 8.65 x 10^20 molecules CO2

X = 0.0632 g

So, 0.0632 g x (1 pound/453.592 pounds) = 1.39x10^-4 pounds

Answer: 1.39x10^-4 pounds
