How can a 0.1 M Sodium Sulfate solution be prepared from Sodium Sulfate powder (# 9434706)?
A 0.1 Molar solution contains 0.1 mole of dissolved solute, sodium sulfate in this case, per Liter of solution. To prepare a 0.1 M Na2SO4(aq) you will need to weigh out 14.2 g of Na2SO4 powder (0.1 M x 142.04g/mol) and dissolve it in enough water to make 1 L of solution. We recommend the solution be prepared in a volumetric flask, if available.
