1. 1 g of Ag(s) [Atomic mass of Ag = 108] 2. 1 g of Mg(s) [Atomic mass of Mg = 24] 3. 1 g of O ₂ (g) [Atomic mass of O = 16] 4. 1 g of Li(s) [Atomic mass of Li = 7]

Answer: 4. 1 g of Li(s) [Atomic mass of Li = 7] Number of atoms is proportional to moles of atoms = mass / atomic mass (all masses are 1 g). Ag: 1/108=0.0093 Mg: 1/24=0.042 O₂ : 1/32 mol molecules =1/16=0.0625 mol atoms Li: 1/7=0.143 Li gives the most atoms, option (4).

Best answer

Answer: 4. 1 g of Li(s) [Atomic mass of Li = 7]

Number of atoms is proportional to moles of atoms \(=\) mass / atomic mass (all masses are 1 g).

Ag: \(1/108=0.0093\)
Mg: \(1/24=0.042\)
\(\mathrm{O_2}\): \(1/32\) mol molecules \(=1/16=0.0625\) mol atoms
Li: \(1/7=0.143\)

Li gives the most atoms, option (4).
