How many moles of h2o will be produced by 7.37moles of n2h4?
n2h4 + 2h202 > n2 + 4h20

n H2O = 29.48 mol

Explanation:

N2H4 + 2H2O2 → N2 + 4H2O

⇒ n H2O = ( 7.37 mol N2H4 )( 4 mol H2O / mol N2H4 )

⇒ n H2O = 29.48 mol

How do we find the answer?

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.
