Answer:
Mg₃N₂
Explanation:
The empirical formula of a chemical compound is defined as the simplest positive integer ratio of atoms present in a compound. Using molecular mass of Mg (24,305g/mol) and mass of nitrogen (14,006g/mol), moles of each element are:
0,73g × (1mol / 24,305g) = 0,03 moles of Mg
0,28g × (1mol / 14,006g) = 0,02 moles of N
Dividing each value in 0,01 to obtain natural numbers:
0,03 moles of Mg / 0,01 = 3
0,02 moles of N / 0,01 = 2.
Thus, empirical formula is: <em>Mg₃N₂</em>

22.4 liters I think because 22.4 liters is at stop
Thus 3 moles of ions are released when samples dissolves definitely in water.
Water (H2O) is made from 2 atoms of hydrogen and 1 atom of oxygen. A mole of water molecules would be 2 moles of hydrogen atoms plus 1 mole of oxygen atoms.
<h3>How many ions are in a mole?</h3>
One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions). The variety 6.022 × 10²³ is acknowledged as Avogadro's number or Avogadro's constant.
<h3>How plenty is a mole of water?</h3>
18.0146 grams
The atomic mass of hydrogen is 1.0078 and the atomic mass of oxygen is 15.999, so the mass of a mole of water is two x 1.0078 + 15.999. Therefore, a mole of water, or 6.022 x 1023 molecules, weighs 18.0146 grams.

Answer:
The answer to your question is C₂ = 0.16 M
Explanation:
Data
Volume 1 = V1 = 200 ml
Concentration 1 = C1 = 0.778 M
Concentration 2 = C2 = ?
Volume 2 = 1 l
Formula
C₁V₁ = C₂V₂
Solve for C₂
C₂ = C₁V₁ / V₂
Process
1.- Convert volume 1 to liters
1000 ml --------------------- 1 l
200 ml --------------------- x
x = (200 x 1) / 1000
x = 200 / 1000
x = 0.20 l
2.- Substitute the values in the formula
C₂ = (0.778 x 0.20) / 1
3.- Simplification and result
C₂ = 0.156 M
