264.28 g


A molar solution contains one mole of solute per litre of solution. So 2 litres of 1 molar solution will contain 2 moles of solute in total.

It means you need to dissolve 2 moles ammonium sulphate in approximately 2 litres of water, then once dissolved, make the total volume up to 2 litres in a volumetric. Molar mass of ammonium sulphate is 132.14 g/mol, so the amount that needs to be dissolved is 2 x 132.14 = 264.28 g.
