Show work please for How many moles of AL are in 2.16 mol of Al2O3

Answer 1

you multiply the amount of moles by the amount of atoms in the compound.

Answer 2

So you do this?
2 mol times 6.02 times 10^23 + 3 mols times 6.02 times 10^23. Then what?

Answer 3

no, sorry i should've been more specific. \(\Large Al_\color{red}2O_3\)

the number of atoms in the formula, which would be 2 for Al.

Answer 4

So 2 times 6.02 times 10^23 then what? This divided by 2.16 mols?

Answer 5

lol no. you simply multiply the amount of atoms in the formula unit (which is 2) by the amount of moles.

2 * 2.16 =
