Question

Constants I Periodic Table Part A Ttanium occurs in the magnetic mineral imenite (FeTiOs). which is often found mixed up with sand The ilmenite can be separated from the sand with magnets. The titanium can then be extracted from the ilmenite the second reaction is carried out with an 87 0 % yield, what mass of titanium can be obtaine the ilmenite-sand micture? eTiO,(o) + 3CI, (o)+3C(o)-+3C0(a) + FeCI,(o) + TIC,() TiCL ()+2Mg(s)+2MgCl() + Ti(s) Suppose that an imenite-sand mixture contains 21 8 % imenite by mass and that the first reaction is carried out with a 90 7 % yield Express your answer with the appropriate units. m Value Units IT Submit Request Answer

Explanation / Answer

The question is incomplete, the mass of sample is missing in the problem

Let the mass of sample be x

Then mass of liminite will be 21.7% of x = 0.217x

Molar mass of limenite = 151.7 m/mol

Number of moles of limenite = 0.217x/151.7 gm/mol

Now first reaction yieid is 90.7%, hence moles of TiCl4 formed = 0.217x/151.7 * 90.7/100

Now second reaction has 87.0% yield

Hence moles of Ti formed = 0.217x/151.7 * 90.7/100 * 87.0/100

Mass of Ti formed = number of moles * molar mass = 0.217x/151.7 * 90.7/100 * 87.0/100 * 47.8 = 0.05395x

Hence substiute the value of x and get the answer
