4a. In the gravimetric analysis of determination of loss of water molecules of hydration from a hydrated salt, identify any one possible mistake, and one proper way to fix it. b.To determine the number of moles of the water of crystallization (n) of a hydrated salt, a student took a sample of 5.94 g of a Cobalt(II)chloride hydrate. The student heated the sample over a burner until constant mass. After cooling, he found that the mass of the remaining dehydrated salt was 4.65 g. i. Determine the mass of water lost by the sample. And the Determine the number of moles of anhydrous Cobalt(II)chloride and water.
