What is the gram atomic mass of an element whose mass of one atom is 3.9853 10⁻²³ g ?

Options

  1. A23 g
  2. B24 g
  3. C27 g
  4. D16 g

Correct answer

B. 24 g

Step-by-step solution

Gram atomic mass is the mass of one mole of atoms of the element. Gram atomic mass = Mass of one atom N_A Given mass of one atom = 3.9853 10⁻²³ g N_A = 6.022 10²³ mol ⁻¹ Gram atomic mass = 3.9853 10⁻²³ 6.022 10²³ Gram atomic mass = 23.999 24 g Answer: 24 g
