Calculate the percent by mass of water in your sample of hydrated copper (II) sulfate. Solution: 1) Determine mass of water driven off: 4.31 − 3.22 = 1.09 g of water. Ciklopea.net. All these concepts were learned in class, and this The term, empirical, means that it is based on observed data rather than on theory. From this, we can calculate the ratio of salt to water (by calculating the molar and stoichiometric ratios), and the percentage of water (by mass) within the hydrated salt (by dividing the mass of the water, by the mass of the hydrated salt, then multiplying the resulting decimal by 100). By measuring the compound before heating and after, the amount of water in the original hydrate can be determined and the formula discovered. Determining the Formula of a Hydrate. Its formula … share data. Virtual Lab: Formula of a Hydrate Background: Hydrates are ionic compounds (salts) that have a definite amount of water (water of hydration) as part of their structure.
