1
Q
what is a mole
A
amount of a substance that contains the same number of particles as the number of carbon atoms in exactly 12g of carbon 12
2
Q
why do we put Ar in grams value
A
because it would be easier to visualize and calculate than using one single atom and would still have the same value since 1 gram of hydrogen and 16 grams of oxygen (making oxygen still 16x more than hydrogen)
