if one knows the mass and the molar mass of product D in a chemical reaction, one can determine the mass of product D procued by using the?

Number of moles

Explanation:

Using the number of moles in chemical reactions, we can determine the quantity of products and even the reactants that are combining to form them.

The number of moles is derived using the expression below is;

     Number of moles  =

Once we establish the number of moles of any of the specie given from the mass and molar mass, we can relate it to any other species.
