How many lithium atoms are in 4.5 moles of li?

Mwahaha, the sciences, my domain...

The solution to this problem is actually very, very simple.

To find the number of atoms in a given number of moles, we simply multiply by Avogadro's constant.

The value of Avogadro's constant is 6.022 x 10²³

Number of Li atoms = moles x Avogadro's constant

Number of Li atoms = 4.5 x 6.022 x 10²³

Number of Li atoms = 2.7099 x 10²⁴

Number of Li atoms = 2.71 x

True, the standard unit for volume is liters which can be represented by either a lower case "l" or a capital "l"
