Ilmenite (FeTiO₃)is the primary ore from which the element titanium (Ti)is isolated. What is the percentage of titanium by mass in this mineral?

Question

Quizplus · Accepted Answer

To find the percentage of titanium in ilmenite, we need to calculate the molar mass of the compound, which is: FeTiO₃= (1xFe) + (1xTi) + (3xO) + (1xS) + (1xU) + (1xB) FeTiO₃= 55.85 + 47.87 + (3x16.00) + 32.06 + 238.03 + 10.81 = 383.62 g/mol The molar mass of Ti is 47.87 g/mol. So, the percentage of titanium in ilmenite can be calculated as: (47.87 g/mol / 383.62 g/mol) x 100% = 12.5% Therefore, the best choice is B, which represents 32%.
