Question

Which has maximum number of atoms ?

• A. 24 g of C
• B. 56 g of Fe
• C. 27 g of Al
• D. 108 g of Ag

Answer 1

The correct option is A 24 g of C

We know that, 1 mole of an atom contains $6.023\times {10}^{23}$ number of atoms

A. 24 g of C,

moles of carbon = $\frac{24}{12}=2$

B. 56 g of Fe

moles of Fe = $\frac{56}{56}=1$

C. 27 g of Al

moles of Al = $\frac{27}{27}=1$

D. 108 g of Ag

moles of Ag = $\frac{108}{108}=1$

so, Carbon has maximum number of moles and hence conatins maximum number of atoms.
