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!
<span> </span><span><span>Colored ions indicate the presence of a transition metal.
Transition metals display colors because of their incompletely filled d
orbitals. As the transition metal absorbs a particular wavelength of
light to raise the electron orbital, it causes the light that passes
through the solution to emit a color.</span></span>
Answer:
As a compound maybe, I'm not quite sure.
sorry and good luck.
Answer:
Your missing the entire Transitional Metal group as well as all the Lanthanides and Actinides.
Explanation:
The groups are:
Alkali metals.
Alkaline earth metals.
Transitional metals.
Crystallogens.
Pnictogens.
Chalcogens.
Halogens.
Noble gases.
<span>Ionic compounds form crystal lattices, not molecules. The term formula unit is used to indicate the simplest whole-number ratio of ions in the compound.</span>
