A sample of ammonium phosphate (NH4)3PO4 contains 3.18 moles of hydrogen atoms. calculate the no. of moles of oxygen atoms present in the sample? pl also show the process of solving it.
kvnmurty:
from the formula we see that, there are 12 atoms of hydrogen or 6 * H2 or 6 moles of Hydrogen.... and there are O4 or 2 moles of O2... Thus the number of moles of oxygen in a sample will be 1/3 rd of that of Hydrogen.

Thanks for asking the question!
ANSWER::
In the problem we can see that the no. of oxygen atoms is 3 times lower than the hydrogen atom and there are 3.18 moles of hydrogen atoms.
So,
Moles of oxygen atoms present in sample is= 3.18/3 = 1.06 moles
