Answer:
7.1 moles Cl₂
Explanation:
To solve this problem we will use Avogadro's number (Aₙ), which tells us how many molecules (or atoms) are present in 1 mol of any given substance
Aₙ = 6.023 x 10²³ molecules/mol
With that in mind now we proceed to convert molecules into moles:
4.28 x 10²⁴ molecules Cl₂ ÷ 6.023 x 10²³ molecules/mol = 7.1 moles Cl₂
7.1 moles Cl₂
Avogadro's number, number of units in one mole of any substance (defined as its molecular weight in grams), equal to 6.023 x 10²³.
It relates to the number of constituent particles in a sample with the amount of substance in that sample.
Lets convert molecules into moles:
4.28 x 10²⁴ molecules Cl₂:
[tex]\frac{4.28*10^{24}}{60.22*10^{23}} =7.1 \text{moles}[/tex]
Thus, the number of moles of Cl₂ will be 7.1.
