Answer:

It's whatever you want it to be. You need more detail.

Explanation:

#%" Yield"# #=# #("Moles of product")/("Moles of reactant") xx 100%#.

This assumes a 1:1 reaction, which of course not all reactions are. You have collected a mass of #NiO#, but we don't know from where you got it. Was it from combustion of nickel metal? We need to know the identity AND the mass of the starting material.
