The density of \( \mathrm{KCl} \) is \( 1.9893 \mathrm{~g} \mathrm{~cm}^{-3} \) and the length of a side unit cell is \( 6.29082 \AA \) as determined by X-Rays
\( \mathrm{P} \) diffraction. The value of avogadros number

VV calculated from these data is-
(1) \( 6.017 \times 10^{23} \)
(2) \( 6.023 \times 10^{23} \)
(3) \( 6.03 \times 10^{23} \)
(4) \( 6.017 \times 10^{19} \)
