320.0 g of NaCl would contain how many formula units? (Molar mass of
NaCl is 58.44 g/mol) *

Formula unit = 32.9746×10²³

Explanation:

Given:

Mass of NaCl = 320 g

Molar mass of  NaCl = 58.44 g/mol

Find:

Formula unit

Computation:

Formula unit = [Mass of NaCl / Molar mass of  NaCl]Avogadro's number

Formula unit = [320 /58.44]6.022×10²³

Formula unit = 32.9746×10²³

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
