    First calculate number of Nitrogen atoms contained by 1 mole of Zn (NO₃) ₂,

    As one formula unit of Zn (NO₃) ₂ contains 2 Nitrogen atoms, then one mole of Zn (NO₃) ₂ will contain,

    = 2 * 6.022 * 10²³

    = 1.20 * 10²⁴ Atoms of Nitrogen / mole

    Now, calculate number of Nitrogen Atoms in 0.150 moles of Zn (NO₃) ₂.

    As,

    1 mole of Zn (NO₃) ₂ contained = 1.20 * 10²⁴ atoms of N

    Then,

    0.15 mole of Zn (NO₃) ₂ will contain = X atoms of N

    Solving for X,

    X = (0.15 mol * 1.20 * 10²⁴ atom) : 1 mol

    X = 1.80 * 10²⁴ Atoms of Nitrogen

    Result:

    So, 0.15 mole of Zn (NO₃) ₂ contains 1.80 * 10²⁴ atoms of Nitrogen.
