Formula Unit

Postby Andrea_Torres » Sun Oct 06, 2019 9:54 pm

In the homework it referred to formula unit. Is formula unit any different mathematically than a molecule or atom? Will it affect any of my calculations?

A formula unit refers to the lowest whole number ratio of ions in an ionic compound. For example, NaCl is the formula unit for the ionic compound sodium chloride. 1 mole contains 6.022 X 10^23 of any units (formula units included).

No, it is not mathematically different than molecules or atoms. Use avagodro's number and it won't impact your calculations.

No, it just essentially means to use Avogadro's number in your calculations.
