A 10.00 g sample of MgSO4.7H2O (246.48 g mol) was heated in an oven at 105°C until all the waters of hydration was evaporated off to generate MgSO4 (anhydrous). The sample was then dissolved in 250 mL of distilled water and diluted to a final volume of 0.5 L. The amount of SO42 in parts per million (ppm) in the final solution is: Molar masses in g mol: MgSO4.7H₂O = 246.48; H₂O = 18.02
