Question

One mole of CO2 contains (A)  3 g atoms of C O 2  (B)  18.1× 1023 molecules of C O2  (C)  6.02× 1023 atoms of O  (D)  6.02× 0 23 atoms of C

Tardigrade Admin · Accepted Answer

One mole =6.02 × 1023 molecules/atoms/ions. ∵ C O2 molecule has one C and two oxygen atoms. ∴ contains 6.023 × 1023 atoms of C and 6.023 × 1023 molecules of O2.

Q. One mole of $C O_{2}$ contains

$3 g$ atoms of $C O_{2}$

$18.1 \times 1 0^{23}$ molecules of $C O_{2}$

$6.02 \times 1 0^{2} 3$ atoms of $O$

$6.02 \times 0^{23}$ atoms of $C$

One mole $= 6.02 \times 1 0^{23}$ molecules/atoms/ions.
$∵ C O_{2}$ molecule has one $C$ and two oxygen atoms.
$∴$ contains $6.023 \times 1 0^{23}$ atoms of $C$ and $6.023 \times 1 0^{23}$ molecules of $O_{2}$ .
