Determine the number of moles (in mol) of oxalate ions in 5.01×10-3 g of ammonium oxalate.
+37084 C₂H₈N₂O₄ is ammonium oxalate
MW = 12 + 12 + 8 + 14 + 14 + 16 + 16 + 16 + 16 = 124 gm / mole
5.01 x 10^-3 gm / 124 gm/mole = 4.04 x 10^(-5) moles of ammonium oxalate
There is one ion of oxalate per ammonium oxalate molecule, so the number of oxalate ions
is the same
