Mass of one sodium atom
The atomic mass of sodium is given as 23 a.m.u. which means that the mass of one sodium atom is 23/6.022 × 10^23 g.
Mass of 3.01 × 10^23 sodium atoms
To find the mass of 3.01 × 10^23 sodium atoms, we need to multiply the mass of one sodium atom by the given number of atoms.
Mass of 3.01 × 10^23 sodium atoms = (23/6.022 × 10^23 g) × (3.01 × 10^23)
= 11.5 g
Therefore, the correct answer is option D, 11.5 g.
