1. The problem statement, all variables and given/known data
How many moles of MgIn2S4 can be made from one gram each of Mg, In, and S? Atomic masses are given.
2. Relevant equations
Moles = mass/molecular mass
3. 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?
