When MoO3 and Zn are heated together they react

3Zn(s)+2MoO3(s) --> Mo2O3(s)+3ZnO(s)

What mass of ZnO is formed when 20.0 grams of MoO3 is reacted with 10.0 grams of Zn?

Do you know how to do limiting reagent problems. This is one? What do you know about them?
Answered by Sarah
I know how to convert moles to mass, atoms, volume etc. and I can find the limiting reagent and the percentage yield of some basic problems.
Answered by DrBob222
This is a limiting reagent problem; you know that because amounts for BOTH reactants are given.
Find the limiting reagent, then convert that, using the coefficients in the balanced equation, to mols of the product. Then convert to g. g = mols x molar mass.
