An unknown inorganic phosphate undergoes first-order dehydration in a drying oven. Initially, the excess water content is measured to be 1.13 mg. After 2.10 days the water content is reduced to 0.488 mg. After 4.40 days, water content is only 0.194 mg. Determine the half-life of hydration under these conditions.
