1s^2 = filled
2s^2 = filled
2p^6 = filled
3s^1 = partially filled (need 2)
3 orbitals are completely filled.
I'm not to sure but try soy
The molecular formula shows the exact number of molecules. Therefor, the empirical formula is the simplest formula of the molecular formula
<u>Answer:</u> The molality of magnesium chloride is 1.58 m
<u>Explanation:</u>
To calculate the molality of solution, we use the equation:
Where,
= Given mass of solute (magnesium chloride) = 75.0
= Molar mass of solute (magnesium chloride) = 95.21 g/mol
= Mass of solvent = 500.0 g
Putting values in above equation, we get:
Hence, the molality of magnesium chloride is 1.58 m
