To determine the number of molecules of NH3 produced from a given mass of H2, you need to follow these steps:

1. Write the balanced chemical equation for the reaction:
N2 + 3H2 → 2NH3

2. Determine the molar mass of H2:
The molar mass of H2 is 2g/mol since hydrogen (H) has a molar mass of 1g/mol, and there are two hydrogen atoms in one H2 molecule.

3. Convert the given mass of H2 to moles:
Use the formula:
Moles = Mass / Molar mass
Moles of H2 = 3.65x10^-4g / 2g/mol

4. Use the stoichiometry of the balanced equation to find the number of moles of NH3 produced:
From the balanced equation, you can see that for every 3 moles of H2, 2 moles of NH3 are produced. Therefore, the moles of NH3 can be calculated as:
Moles of NH3 = Moles of H2 * (2 moles NH3 / 3 moles H2)

5. Convert moles of NH3 to molecules:
The Avogadro's number states that there are approximately 6.022 × 10^23 particles (atoms, molecules) in one mole of a substance. Therefore, to convert moles of NH3 to molecules, you can use the following conversion factor:
Molecules = Moles of NH3 * (6.022 × 10^23 molecules / 1 mole)

By following these steps, you can calculate the number of molecules of NH3 produced from 3.65x10^-4g of H2.

3 moles of H2 produce 2 moles of NH3

3.65*10^-4 g of H2 is 3.621*10^-4 moles H2
That will produce 2.414*10^-4 moles of NH3
2.414*10^-4 * 6.023*10^23 = 1.454*20^20 molecules NH3
