Correct Answer: Mass of ore that contains 200 g of Ti is 617.28 g.
Reason:
Given: Ore contains 32.4% Ti by mass.
It implies that, 100 g of ore ≡ 32.4 g of Ti
Therefore, x g of ore ≡ 200 g of Ti
Thus, x = [tex] \frac{100X200}{32.4} = 617.28 g[/tex]
Hence, mass of ore that contains 200 g of Ti is 617.28 g.
