Do you know your mole equalities? Answer: True or False
1 atom = x g
False! That is a HUGE mass for 1 atom.
1g Ca = 1.66 x atom Ca
False! You can’t have a fraction of an atom.
1 amu = 1.66 x g
True!
1 g Si = atoms Si
False! Again, you can’t have a fraction of an atom.
1 g = x atoms
False! Well, it is true for one element.
1g/mol = x 10 23
False!
1 mol Ca = g Ca
True!
6.022 x g Ca =1 mol Ca
False! Never put Avogadro’s number with grams.
1 mol = x amu
False!
1 mol = 6.022g
False! There are no elements with an atomic mass of 6.022g.
1 atom = x g
False!Still.
1 mol = x g/atom
False!
1 mol = x particles
True!
1amu = x g/mol
1g/mol = x False!
1amu = x g/mol
False!
1 atom Boron =1.795 x g B
True! 10.81g B x 1 mol B =g/atom mol x atoms
