Question

calculate the number of moles in 6.022x10^22 molecules of oxygen

Answer 1

1 mole contains Avogadro number of oxygen molecules.

That is,

6.022 x 10^23 molecules of oxygen indicates 1 mole.

So,

6.022 x 10^22 molecules of oxygen indicates 0.1 moles

Hope it helps!!

Answer 2

Answer: 0.1 moles

Explanation: According to Avogadro's law, 1 mole of every substance contains avogadro's number $(6.023\times 10^{23})$ of particles.

1 mole of $O_2$ contains $6.023\times 10^{23}$ molecules of oxygen.

$6.023\times 10^{23}$ oxygen molecules = 1 mole

Thus $6.022\times 10^{22}$ oxygen molecules=$\frac{1}{6.023\times 10^{23}}\times 6.022\times 10^{22}=0.1 moles$
