The number of atoms in 0.1 mole of a triatomic gas is ( N _ A =6.02 10²³ ~mol ⁻¹ )

Options

  1. A6.026 10²²
  2. B1.806 10²³
  3. C3.600 10²³
  4. D1.800 10²²

Correct answer

B. 1.806 10²³

Step-by-step solution

Number of atoms = number of moles N _ A atomicity aligned & =0.1 6.02 10²³ 3 & =1.806 10²³ atoms aligned
