Question

Calculate the number of moles of $S_8$ present in $3.011\times {10}^{25}$ molecules of $S_8$.

• A. 10
• B. 50
• C. 100
• D. 500

Answer 1

The correct option is B 50

Number of moles $=\frac{Numberofmolecules}{Avogadronumber}=\frac{3.011\times {10}^{25}molecules}{6.022\times {10}^{23}molecules/mol}=50moles$
