How many moles of NH3 would be needed to produce 1.99 x 1025 molecules of H2O? Assume the reaction is 100% efficient and that oxygen gas is present
in excess.

For the reaction shown, calculate how many moles of no2 form when each of the following completely reacts. 2n2o5(g)→4no2(g)+o2(g) part a 1.0 mol n2o5 express your answer using two significant figures. nothing mol m o l request answer part b 5.4 mol n2o5 express your answer using two significant figures.
