Moles of HCl = 0.05 mol
Therefore at a [[ratio]] of 1:1 then 0.05 mol of NaOH are needed.
'' '''concentration of NaOH''' '' = <math>\frac{Moles (mol)}{volume (dm^3)}</math>
Moles of H<sub>2</sub>SO<sub>4</sub> = 0.06 mol
Therefore at a [[ratio]] of 1:2 then 0.12 mol of NaOH are needed.
'' '''concentration of NaOH''' '' = <math>\frac{Moles (mol)}{volume (dm^3)}</math>
Moles of HCl</sub> = 0.15 mol
Therefore at a [[ratio]] of 2:1 then 0.075 mol of Mg(OH)<sub>2</sub> are needed.
'' '''concentration of Mg(OH)<sub>2</sub>''' '' = <math>\frac{Moles (mol)}{volume (dm^3)}</math>
