molarity of the sodium nitrate solution = 0.496 ≈ 0.5 M
Explanation:
First we need to determine the number of moles of sodium nitrate (NaNO₃).
number of moles = mass / molecular weight
number of moles of sodium nitrate = 5.31 / 85 = 0.062 moles
Now we determine the molarity of the solution with the following formula:
molarity = number of moles / solution volume (L)
molarity of the sodium nitrate solution = 0.062 / 0.125 = 0.496 ≈ 0.5 M

JJ Thomson proved John Dalton's theory wrong, as Thomson discovered the electron. This showed that there were particles that were smaller than an atom, despite Dalton claiming that the atom is the smallest unit of matter.
This problem is providing us with the percent composition of a compound containing magnesium, nitrogen, oxygen and water. Thus, the empirical formula is required and found to be Mg(NO₃)₂·6H₂O.
<h3>Empirical formulas</h3>
In chemistry, empirical formulas are used in order to figure out the minimum whole-number representation of a molecular formula, which contains the actual number of atoms.
Thus, we start determining it by assuming the given percentages as masses and calculating the moles with the atomic or molar mass of the involved species:
Next, we divide by the 0.386 as the smallest number of moles in order to determine their subscripts in the chemical formula:
Hence, the empirical formula turns out to be Mg(NO₃)₂·6H₂O, which is actually a hydrate (hexahydrate).
