Question

How many moles are present in one 1 atom of carbon?

• A. $1.0$
• B. $0.50$
• C. $0.166\times {10}^{-23}$
• D. $6.023\times {10}^{23}$

Answer 1

The correct option is C $0.166\times {10}^{-23}$

According to the mole concept, one mole of anything contains the same number of atoms as are present in 12 grams of C-12 sample i.e. $6.023\times {10}^{23}$ atoms.

Number of moles = $\frac{numberofparticles}{Avogadro\text{'}snumber}=\frac{1}{6.023\times {10}^{23}}=0.166\times {10}^{23}moles$
