Vedclass · Answer

(B) We know that $1 \, mol$ of any substance contains $6.022 	imes 10^{23}$ particles (Avogadro's number).To find the number of moles of oxygen atoms,we use the formula:$	ext{Number of moles} = \frac{	ext{Given number of atoms}}{	ext{Avogadro's number}}$$	ext{Number of moles} = \frac{2.58 	imes 10^{24}}{6.022 	imes 10^{23}}$$	ext{Number of moles} = \frac{25.8 	imes 10^{23}}{6.022 	imes 10^{23}} \approx 4.28 \, mol$Therefore,the sample contains $4.28 \, mol$ of oxygen atoms.

$A$ sample of vitamin $C$ is known to contain $2.58 \times 10^{24}$ oxygen atoms. How many moles of oxygen atoms are present in the sample?
