Question

How many molecules (not moles) of NH3 are produced from 5.01×10−4 g of H2?

Answer 1

1. Set up your balanced equation.

3H2 + N2 ---> 2NH3

Answer 2

If you look at what I wrote, here's how you can set this up.

1. You must first find the balanced chemical reaction.

2. You must convert grams of your substance in this case hydrogen gas into moles.

3. You must multiply the molar ratio in this case NH3/H2 which is 2/3 ensuring that the compound you want NH3 is in the numerator, and while the compound you don't want, H2 is in the denominator.

4. You get the number of moles of NH3.

5. You know that 1 mole has 6.02x10^23 particles.

6. Set up a ratio cross multiply and you get the number of particles.
