Only a few ions (in comparison to others that totally break apart)
1/12 = 1 : 12 = 0.08333 x 100 = 8.33 %
Here, Equation: 2NaOH + H₂SO₄ → Na₂SO₄ + 2H₂O
We know, Concentration (c) = Number of moles(n) / Volume (v)
Substitute the given values,
0.02 = n / 0.3 [ 300 mL = 0.3 L ]
n = 0.3 * 0.02
n = 0.006
Now, According to stoichiometry, There is 1 Molecule of Sodium sulfate produces for every 2 molecules of NaOH.
So, Number of Moles of Na₂SO₄ = 0.006/2 = 0.003
Given mass = Molar mass * Number of moles
M = 142.04 * 0.003
M = 0.426 g
In short, Your Answer would be: 0.426 g
Hope this helps!
