IIT/JEE Chemistry Practice #1: Avogadro's Number/Moles

The video tutorial covers two main problems related to Avogadro's number and the mole. The first problem involves calculating the total number of electrons in 18 milliliters of water by converting volume to mass, then to moles, and finally using Avogadro's number. The second problem requires determining which of several compounds contains the largest number of molecules by converting given masses to moles and comparing them.

What is Avogadro's number and why is it significant?

Which of the following compounds contains the largest number of molecules?

How do you determine the number of moles from a given mass of a substance?
