An atom forms face centered cubic crystal with density

d=8.92 \mathrm{~g} / \mathrm{mL}

and edge length

a=3.6 \times 10^{-8} \mathrm{~cm}

. The molecular mass of atom in amu is

View answer and explanation

Correct option: B

63 \mathrm{~amu}

Option B (

63 \mathrm{~amu}

) is correct because the molecular mass can be calculated using the density, edge length, Avogadro's number, and the number of atoms per FCC unit cell.
