Calculate the mass of 1 nanomol of ammonia .

These questions have statement I and statement II. Of the four choices given below, choose the one that best describes the two statements. Statement I: It is obvious that dimensions of all the terms must be the same in any mathematical relation between physical quantities. Statement II: Dimensions of a physical quantity are the powers to which the fundamental units should be raised to represent the unit of that physical quantity.
