Question

what weight of co2 contains as many molecules as in 16g o2


​

Answer 1

Answer:

22g

Explanation:

16g of O2 is half a mole of O2. Assuming STP conditions, 1/2 a mole of O2 contains 3.011*10^23 molecules of oxygen.

Molecular weight of CO2 is 44g.

1/2 a mole of CO2 will contain the same number of CO2 molecules as 1/2 a mole of O2.

Therefore, 22g of CO2 is the answer
