Hey there !
Molecular Weight: 262.86 g/mol
Volume in liters : 1,000 mL => 1,000 / 1000 => 1 L
Number of moles of solution :
number of moles = volume x molarity
number of moles = 1 x 0.3 => 0.3 moles
Therefore:
1 mole Mg₃(PO₄)₂ ------------------- 262.86 g
0.3 moles ----------------------------- mass of Mg₃(PO₄)₂ ??
mass of Mg₃(PO₄)₂ = 0.3 x 262.86 / 1
mass of Mg(PO₄)₂ => 78.858 g
Hope this helps!
Answer:
- <em>sp³ hydbridization</em> is the formation of 4 equal hybrid orbtials (same characteristcs) by the hybridization ("mixture") of two different kind of orbitals: 1 type s orbtial and 3 type p orbitals.
Explanation:
This hybridization is the result of the rearragement of the valence electrons that originally are in s and p orbitals, forming the new hybrid orbitals (sp³).
This is easily explained with carbon atom.
- Carbon has atomic number 6, hence it has 6 electrons.
- Thus, the electron configuration of carbon is: 1 s² 2s² 2p².
- So, there are four valence electrons that are in the 2s and 2p orbitals.
- The hybridization consists in that the four valence electons, instead of remain in two different energy levels (s and p) will form 4 orbitals, named sp³, each with the same energy.
- In summary the four electrons originally distributed as 2s² 2p² will be located as 2 sp³.
