Which of the following has the largest number of atoms?
- A \(1 \mathrm{~g}\) of \(\mathrm{Ag}\)
- B \(1 \mathrm{~g}\) of \(\mathrm{Fe}\)
- C \(1 \mathrm{~g}\) of \(\mathrm{Cl}_{2}\)
- D \(1 \mathrm{~g}\) of \(\mathrm{Mg}\)
Answer & Solution
Correct Answer
(D) \(1 \mathrm{~g}\) of \(\mathrm{Mg}\)
Step-by-step Solution
Detailed explanation
Hint: Number of atoms of \(\mathrm{Ag}=\frac{1}{108} \times \mathrm{N}_{\mathrm{A}}=0.009 \mathrm{~N}_{\mathrm{A}}\) Number of atoms of \(\mathrm{Fe}=\frac{1}{56} \times \mathrm{N}_{\mathrm{A}}=0.0178 \mathrm{~N}_{\mathrm{A}}\) Number of atoms of…
