NEET · Chemistry · STD 11 - 1. Some basic concept of chemistry
Which one of the following has maximum number of atoms\(?\)
- A \(1 g\) of \(Li ( s )\) [Atomic mass of \(Li =7]\)
- B \(1 g\) of \(Ag ( s )\) [Atomic mass of \(Ag =108]\)
- C \(1 g\) of \(Mg ( s )\) [Atomic mass of \(Mg =24]\)
- D \(1 g\) of \(O _{2}( g )\) [Atomic mass of \(\left. O =16\right]\)
Answer & Solution
Correct Answer
(A) \(1 g\) of \(Li ( s )\) [Atomic mass of \(Li =7]\)
Step-by-step Solution
Detailed explanation
Number of atoms \(=\frac{w}{\text { molar mass }} \times N _{ A } \times\) atomicity
