When a sample (0.6271 g) of impure magnesium chloride (MgCl2, MM = 95.211) was dissolved in water and treated with an excess of silver nitrate (AgNO3, MM = 137.874), 0.8449 g of silver chloride (AgCl, MM = 143.321) was precipitated. Calculate the percentage magnesium chloride in the original sample. [You can assume no other reactions interfere with this precipitation reaction.]
