Vedclass · Answer

(D) The chemical formula of phosphorus trichloride is $PCl_{3}$.Each molecule of $PCl_{3}$ contains $1$ atom of phosphorus and $3$ atoms of chlorine,totaling $4$ atoms per molecule.Therefore,$1 \, mol$ of $PCl_{3}$ contains $4 \, mol$ of atoms.For $1.4 \, mol$ of $PCl_{3}$,the total number of moles of atoms is $1.4 	imes 4 = 5.6 \, mol$.Using Avogadro's number $(N_{A} = 6.022 	imes 10^{23} \, mol^{-1})$,the total number of atoms is $5.6 	imes 6.022 	imes 10^{23} = 3.37232 	imes 10^{24}$ atoms.Rounding to the nearest provided option,the correct answer is $3.3712 	imes 10^{24}$.

$1.4 \, mol$ of phosphorus trichloride $(PCl_{3})$ are present in a sample. How many atoms are there in the sample?
