The toxic pigment called whte lead pb3(oh)2(co33)2 has been replaced in white paints by rutile, tio2. how much rutile can be prepared from 379 g of an ore that contains 88.3% ilemnite (fetio3) by mass?
2ftio3 + 4hcl + cl2 ? 2fecl3 + 2tio2 + 2h2o

Answer : The mass of prepared can be 176.48 grams.

Explanation :

First we have to calculate the mass of .

As we are given that the 88.3 % by mass. That means, 88.3 grams of present in 100 grams of solution.

Now we have to calculate the moles of .

Molar mass of = 151.7 g/mole

Now we have to calculate the moles of .

The balanced chemical reaction is,

From the balanced reaction, we conclude that

As, 2 moles of react to give 2 moles of

So, 2.206 moles of react to give 2.206 moles of

Now we have to calculate the mass of .

Molar mass of = 80 g/mole

Therefore, the mass of prepared can be 176.48 grams.
