Question

How many moles are in 4.4g
of CO2?​

Answer 1

Explanation:

Molar mass of oxygen gas is 2⋅15.999gmol=31.998gmol . So when you add them together to get the molar mass of CO2 you get 44.009gmol . We also know that there are around 6.02⋅1023 atoms in a mole (Avogadro's number).

Answer 2

Answer: 0.1 moles

Explanation:

No of moles = given wt. / molecular wt.

Here for CO2 molecular mass= 12+(16) 2=44gm

So No. Of moles = 4.4gm/44gm

= 0.1 mole of CO2
