Do you know your mole equalities?. Answer: True or False. 1 atom = 6.022 x 10 23 g. 1 atom = 6.022 x 10 23 g. False! That is a HUGE mass for 1 atom. 1g Ca = 1.66 x 10 -24 atom Ca. 1g Ca = 1.66 x 10 -24 atom Ca. False! You can’t have a fraction of an atom. 1 amu = 1.66 x 10 -24 g.

Do you know your mole equalities? Answer: True or False
1 atom = 6.022 x 1023 g False! That is a HUGE mass for 1 atom.
1g Ca = 1.66 x 10-24atom Ca False! You can’t have a fraction of an atom.
1 amu = 1.66 x 10-24 g True!
1 g Si = 28.08 atoms Si False! Again, you can’t have a fraction of an atom.
1 g = 6.022 x 1023 atoms False! Well, it is true for one element.
1g/mol = 6.022 x 1023 False!
1 mol Ca = 40.08 g Ca True!
6.022 x 1023g Ca =1 mol Ca False! Never put Avogadro’s number with grams.
1 mol = 6.022 x 1023amu False!
1 mol = 6.022g False! There are no elements with an atomic mass of 6.022g.
1 atom = 6.022 x 1023g False! Still.
1 mol = 6.022 x 1023 g/atom False!
1g/mol = 6.022 x 1023 False!
1amu = 6.022 x 10-23 g/mol False!
True! 10.81g B x 1 mol B =g/atom mol 6.022 x 1023atoms
