Question

define molar mass of a molecular substance

Answer 1

In chemistry, the molar mass M is a physical property defined as the massof a given substance (chemical element or chemical compound) divided by the amount of substance. The base SI unit for molar mass is kg/mol. However, for historical reasons, molar masses are almost always expressed in g/mol.

Answer 2

Molar mass is the mass that a molecule possess as the sum of mass of all the atoms contained in it. for eg-Water has the formula H2O so its molar mass will be 1*2*16=32
