Finding the molar mass of air

  • #1

Homework Statement



How many moles of MgIn2S4 can be made from one gram each of Mg, In, and S? Atomic masses are given.

Homework Equations


Moles = mass/molecular mass


The Attempt at a Solution



I have found the moles of each entity.

Mg - 0.04167 moles
In - 0.00871 moles
S - 0.03125 moles

Do I find the moles of the compound mentioned by adding the moles I have found here or do I say that the mass of the strange compound I have here is 3 g and that the moles formed are 3/(32 + 24 + 114.8 = molar mass of MgIn2S4)?

How do I proceed?

I'm sorry for the misleading title of the thread. It should be finding the number of moles!
