Moles

 ???

An oxide of a metal, Q, has the formula QO4. The oxide reacts with excess H2 to yield the free metal ad H2O according to the following balanced reaction.

QO4 (s) + 4H2 (g) --> Q (s) + 4H2O (L)

How many moles of QO4 are consumed?

What is the molar mass of QO4?

Question as given seems to be impossible to do. Have you listed all information?
