Answer:

The mass percent refers to the mass of an element in a compound. It is one of the ways of expressing concentration. The mass percent of the solution provides the percentage of the amount of solute present in grams of solution.

The mass percentage of S=40.06 % and the molar mass of S= 32. By applying the formula of mass percent,we can calculate the molar mass of M.

The molar mass of M=159.76-64=95.76

We know that the element of molybdenum has molar mass of 96. Therefore, the element M is Molybdenum.
