Step 1
First, we need to find the density of NaCl. To do this, we can use the formula: Density = (mass of Na + mass of Cl) / (lattice constant)^3 Show more…

The spacing of adjacent atoms in a NaCl crystal is 0.282$\mathrm { nm }$ and the masses of the atoms are $3.82 \times 10 ^ { - 26 } \mathrm { kg } ( \mathrm { Na } )$ and $5.89 \times 10 ^ { - 26 } \mathrm { kg } ( \mathrm { Cl } ) .$ Use this information to calculate the density of sodium chloride.
Determine the lattice constant of $\mathrm{NaCl}$ crystal. The molecular weight of $\mathrm{NaCl}$ is $58.44$ and the density is $2.167 \mathrm{~g} \mathrm{~cm}^{-3}$.
