Titanium$($IV$)$ oxide $(Ti{O}_2)$ is a white substance produced by the action of sulfuric acid on the mineral ilmenite $(FeTi{O}_3)$ :

$FeTi{O}_3+H_{2}S{O}_{4}longrightarrowTi{O}_2+FeS{O}_4+H_{2}O$

Its opaque and nontoxic properties make it suitable as a pigment in plastics and paints. In one process, $(7500+Y)kg$ of $FeTi{O}_3$ yielded $2675kg$ of $Ti{O}_2.$ What is the percent yield of the reaction?

For preparation of $(200+Y)ml,2\mathrm{.}8M$ solution from the following solutes, how many grams is required?

I. Methanol

II$.$ Sodium Carbonate

Y$=40$
