ummm one mole of Na would be 23 g[or 22.99?] and one mole of 2NaO would be 46 g Na+32g O or 78g 2NaO...in other words, one mole is equal to the molar mass of the elements present

The common thing said, and easiest to remember is a mol is the number of atoms in 12.0 g of Carbon-12. And there 6.022 times 10 to the 23rd. Which is a lot of atoms. That's a lot of anything.

you can convert grams to moles by using avogadro's number..
# of grams ____1mole_____________X 6.022x10 23
Molar mass of a substance
