How many moles of carbon dioxide are present in #5.44 × 10^22# molecules of this compound?

Answer 1

Natalie Anton

#"Moles of "CO_2# #=# #(5.44xx10^22)/(6.022140857(74)xx10^23*mol^-1)#

So the answer is approx. #0.10*mol#.

In this molar quantity, how many moles of oxygen atoms are there?

To calculate the number of moles of carbon dioxide present in 5.44 × 10^22 molecules, you can use Avogadro's number, which is approximately 6.022 × 10^23 molecules per mole.

Number of moles = Number of molecules / Avogadro's number

Number of moles = (5.44 × 10^22 molecules) / (6.022 × 10^23 molecules/mole)

Number of moles ≈ 0.0903 moles
