Calculate the value of Avogadros number from the following data:
Density of \( \mathrm{KF}=2.48 \mathrm{~g} \mathrm{~cm}^{-3} \).
Distance between \( \mathrm{K}^{+} \)and \( \mathrm{F}^{-} \)in \( \mathrm{KF}=269 \mathrm{pm} \) (At mass \( \mathrm{K}=39, \mathrm{~F}=19 \mathrm{amu} \) )
\( \mathrm{P} \)
