Alloys are solid mixtures of metals prepared by smelting, namely a metal and one or more elements are added to a vessel that is heated above the highest melting point among the elements and the resulting liquid mixture is slowly cooled until it solidifies into a solid with homogeneous composition. Calculate the masses of Mg, Cu, and Ni needed to form 1.000 kg of an alloy with empirical formula given by Mg85Cu5Ni10. Even if this alloy is not a compound in the regular sense (it is a Berthollide, instead of a Daltonide and as such it does not satify the law of definite proportions), you can still use the ICE table and the principles of stoichiometry to solve this problem.
