Titanium(IV) oxide (TiO2) is a white substance produced by the action of sulfuric acid on the mineral ilmenite (FeTiO3).FeTiO3 + H2SO4 → TiO2 + FeSO4 + H2OIt is opaque and its nontoxic properties make it suitable as a pigment in plastics and paints. In one process 8.65 ✕ 103 kg of FeTiO3 yielded 3.47 ✕ 103 kg of TiO2. What is the percent yield of the reaction?

Explanation:

Below is an attachment containing the solution.

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%
