Calculate the number of atoms in 24g of CO2 gas

Answers

Answered by Rythm14

Given = 24g

Atomic weight of carbon = 12g

No. of moles = given weight / atomic weight

= 24/12

= 2 mol

Now,

No. of moles = no. of atoms / Avogadro's number also.

So,

2 = no.of atoms / 6.02 × 10^23

No. of atoms = 12.04 × 10^23

Rythm14: change the atomic mass to 44 not 12

Rythm14: then it will be 44/12

Rythm14: thats 3

Rythm14: then 3 X 6.023 X 10^23

Rythm14: that is 18.069 x 10^23

Humanbeings: wrong

Rythm14: ???????

Humanbeings: it should be 24/44

Rythm14: yeh im so sorryyy ;_;

Rythm14: so then u multiply 1.8 w/ 6.023 X 10^23

Explanation:

given weight= 24g

atomic weight of carbon: 12g

nos. of moles: given weight÷ atomic weight

24÷12

=2 mole

therefore, nos. of atom = 12.04*10^23

Humanbeings: Can't you see CO2 written in question?

Humanbeings: You are considering only C atom

Humanbeings: Are you blind?
