    Hi,

    The density of LiF is 2.56g cm-3. It is made up of cubic array alternate Li+ and F- ions and the distance between these ions is 2.01 Angstrom (2.01 x 10-8 cm). Calculate the Avogadro’s number.Please solve this numerical problem and explain each step. It is already solved in my textbook but is not explained thus I can’t understand please help me.

    Please help.

    I didn’t find the right solution from the Internet.
