The formula weight of a compound is simply equal to the total molar mass.

The molar mass of each elements are:

Mg = 24.305 g/mol

N = 14.0067 g/mol

O = 15.999 g/mol

 

So the total molar mass is:

formula weight = 24.305 + 2 (14.0067) + 6 (15.999)

<span>formula weight = 148.3 g/mol</span>

Compare the strength of the intermolecular forces in solids liquids and gases
telo118 [61]

Intermolecular forces in solids are strongest than in liquids and gases. Gases have the least strong intermolecular forces. Intermolecular forces are weak and are significant over short distances between molecules (determined by Coulomb’s law). The farther away from the molecules the weaker the intermolecular forces. Since molecules in solids are the closest, the intermolecular force between them as the strongest. Conversely, since gas molecules are farthest apart, the intermolecular forces between them are the weakest.

Matter and energy are
Wewaii [24]
When energy transforms into mass, the amount of energy does not remain the same. When mass transforms into energy, the amount of energy also does not remain the same. However, the amount of matter and energy remains the same. ... You would weigh much less on the Moon because it is only about one-sixth the mass of Earth. So the answer is D
