(D) First,calculate the atomic mass of the element:Atomic mass $= \text{mass of one atom} \times N_A = 3.32 \times 10^{-23} \ g \times 6.022 \times 10^{23} \ mol^{-1} \approx 20 \ g/mol$.Next,convert the total mass to grams:$20 \ kg = 20,000 \ g$.Gram atoms (moles) $= \frac{\text{Total mass}}{\text{Atomic mass}} = \frac{20,000 \ g}{20 \ g/mol} = 1000 \ \text{mol}$.
