how many ions are present in 0.5 mol of sodium oxide?
thanks
Answered by DrBob222
There are 6.02E23 molecules present in 1 mol Na2O. In 0.5 mol there will be 0.5 x 6.02E23 molecules.
There are three ions present in 1 molecule Na2O; therefore there will be
0.5 x 3 x 6.02E23 ions present om 0.5 mol Na2O.

thank you
Answered by freddyyyyy!
if the question was asking how many oxide ions would you not multiply it by 3? thank you for your help

No. There is 1 O atom in 1 molecule of Na2O; therefore, mols Na2O = mols O atoms.
In the problem above that's 0.5mol x 6.02E23 molecules/mol = ?
