Question

Vanadinite is a mineral with the chemical formula Pb5(VO4)3Cl and is one of the main industrial
ores that are used for the extraction of elemental vanadium.
) If you start with 1.21 kg of Pb5(VO4)3Cl, what is the maximum number of grams of V that can
be extracted from this ore. HINT: Think about the % composition by mass of V in Vanadinite!
a. 43.2 grams
b. 130 grams
c. 155 grams
d. 173 grams

Answer 15

) Once the vanadium has been extracted it can be used to produce a variety of pure vanadium
oxides. One such oxide was found to contain 56.02% vanadium. What is the empirical
formula of this oxide?
a. V2O2
b. V2O3
c. V2O5
d. V1O3

Answer 17

I got the first part, its 130 g

Answer 18

you know that out of 100g 56.02 g are V, so use the same concept of mass percent composition.
