Calculate the mass in grams of 8.24 x 1024 molecules of CO2

602.25 gm

Explanation:

1 mole of any gas contains 6.02 x 10²³ molecules of gas

6.02 x 10²³ molecules of CO₂ contains 1 mole of CO₂

8.24 x 10²⁴ molecules of CO₂ will contain 8.24 x 10²⁴/ 6.02 x 10²³ moles at STP

13.6877 moles

mol weight of CO₂ = 44 g

13.6877 moles of  CO₂ = 44 g  x 13.6877 g =  602.25 gm.
