Question

How many Nitrogen atoms are in 4 moles of NH3?

Answer 1

Answer:

Since we have the amount of N2 and excess of hydrogen, we only need to work with the amount of N2. As we said before, for every mole of N2 we get 2 moles of NH3 and using this proportions we can make a conversion tool and calculate how many moles of NH3 we obtain from 2.5 moles of N2.One mole of any substance contains 6.022×1023 atoms/molecules. Answer: 1.68×1024 atoms of nitrogen are present in 2.79 mol of NH3.
