The oval surrounding their name was meant to protect them from evil spirits in life and after death. The cartouche has become a symbol representing good luck and protection from evil. Egyptians believed that one who had their name recorded somewhere would not disappear after death. A cartouche attached to a coffin satisfied this requirement.
A single mole can construct 200 mounds over the course of a winter. (Drawing by Jenifer Rees.) Moles construct two kinds of tunnels: surface tunnels and deep tunnels, or runways. Surface tunnels are located 1 to 4 inches below the surface.
So, neon has a molar mass of 20.18 g/mol, which means that every mole of neon has a mass of 20.18 g. Your sample of neon will thus contain 5.9color(red)(cancel(color(black)(g))) * 1 mole Ne/(20.18color(red)(cancel(color(black)(g)))) = 0.2924 moles Ne Now, you know that one mole of any element contains exactly 6.022 * 10^(23) atoms of that element - this is Avogadro's number.
