The only thing I remember from high school chemistry is Avogadro’s number.
The name “Avogadro’s Number” is just an honorary name attached to the calculated value of the number of atoms, molecules, etc. in a gram mole of any chemical substance. Of course if we used some other mass unit for the mole such as “pound mole”, the “number” would be different than 6.022 x 1023
Mmmmm…. homework. Brings back the good old days.
