The question is:
Ilmenite is a mineral that is an oxide of iron and titanium, FeTiO
3. If an ore that contains ilmenite is 6.75% titanium, what is the mass (in grams) of ilmenite in 1.00 metric ton (exactly 1000kg) of the ore?
So I took .0675 x 1000kg = 67.5kg Ti
then...
67.5kg Ti x 1000g Ti/ 1kg Ti x 1 mole Ti/47.88g Ti x 1mole FeTiO
3 / 1 mole Ti x 151.709 g FeTiO
3 / 1 mole FeTiO
3 = 21387.5 g FeTiO
3 = 2.14X10
4g FeTiO
3Only my text says the answer is 2.14X10
5And I can't figure out where I've gone wrong with missing a decimal place....
Thanks for any help you can give me
