Question

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

Answer 1

Step-by-step 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.
