Formula to calculate mass percent is as follows:
(b)
Interpretation: Total mass of Platinol that can be made for
Concept introduction: Law of mass conservation is defined as for an isolated system the mass can neither be created nor destroyed by
Chemical compounds contain its constituent elements in a fixed ratio by mass and it is independent of its origin and the way of preparation, it is known as law of definite proportions.
