What Is the Difference Between Molar Mass and Molecular Weight in HNO3?

Difference between molecular weight and molar mass

Hint : Molar mass of molecules is also called molecular weight . Its unit is gram per mole. We can calculate molar mass of molecule with the help of following rules; ... Molar mass of nitric acid (HNO3) =atomic mass of hydrogen + atomic mass of nitrogen +3× atomic mass of oxygen .

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
