Question

The percent of composition is of nitrogen in the compound (NH4) 2O is 25.8%. Hiw do u check this answer??

Answer 1

I think you need to calculate what the total molecular mass is: nitrogen is 14, hydrogen is 4 so two amonium ions (NH4+) is 36 daltons. Add another 16 for oxygen and you have 52 in total. So the amount of nitrogen is 28 over 52 so I think it's not actually 25.8% unless I've got it wrong.
