What do we mean by #"molar quantities"#? How are these used in stoichiometry, and chemistry problems?
You might have to re-ask this question. I am willing to try to answer. One mole of stuff is equivalent to
The use of the mole specifies the given number. In other circumstances, if we were poultry farmers of bakers, we might use
Why should we choose such a number? Well, it turns out that if we have
From this we develop the idea of equivalent weight, in which a given mass of stuff can be precisely related to an actual number of molecules or atoms. Atomic mass is quoted on the Periodic Table, and the mass in grams is that possessed by a mole, by Avogadro's number of molecules,
And thus for a simple reaction we can make the following predictions:
Anyway, you should review your notes and problems. You are certainly free to post queries. Someone here will help you. Good luck.
See here for an example of an A level problem.
