An industrial chemist prepares a standard solution of ammonium sulfate for agricultural soil analysis. She dissolves exactly 11.25 g of the dry crystalline solid in distilled water and makes the volume up to exactly 450 cm3 in a volumetric flask.
concentration (g dm−3)=mass of solute (g)volume of solution (dm3) \text{concentration (g dm}^{-3}\text{)} = \frac{\text{mass of solute (g)}}{\text{volume of solution (dm}^3\text{)}} concentration (g dm−3)=volume of solution (dm3)mass of solute (g)Calculate the concentration of this ammonium sulfate solution in g dm−3\text{g dm}^{-3}g dm−3.
