How to Calculate the Molar Mass of elements and molecules
Elements: Easy, just look at the periodic table.
Molecules: Add up the masses of the atoms that form the compound.
For example, an oxygen atom weighs 16.00 g/mol according to the periodic table. So an O2 molecule would weigh 2 x 16.00 g/mol = 32.00 g/mol

@Zyra Hour 30 for me. Our teacher sucked, and literally nobody knew what she was going on about. I learned what she *tried* to explain here in just a couple of minutes. She tried comparing moles to eggs and stuff, then going onto pointless comparisons that did nothing but confuse the class.

I'm not trying to sound over-dramatic, but you just saved my entire life. Please, please, please, keep teaching. You explained this (that took my Chemistry teacher two weeks of 45 minute lessons, and I still didn't comprehend) in only 3 minutes. Thank you so so so so so so so so so so so so so so much!!!

When you are adding up molar masses do you always round each one to four significant figures? For example the molar mass on Na is actually 22.989770g on the periodic table but here you rounded to four sig figs 22.99g

@NatsuDragneelBC 8 жыл бұрын

+Gray Fullbuster Standard for Molar mass of a single atom is to round to 4 sig figs. In a molecule calculation you round your final number to how ever many sig figs your initial known number(s) has. So if you don't know for sure what to round it to, 4 sig figs is the way to go.
