Which one of the followings has maximum number of atoms ?

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]

Step-by-Step Solution

Number of Mg atoms = 124×NA\frac{1}{24} \times N_A. Number of O atoms = 132×2×NA\frac{1}{32} \times 2 \times N_A. Number of Li atoms = 17×NA\frac{1}{7} \times N_A. Number of Ag atoms = 1108×NA\frac{1}{108} \times N_A.
