To find the number of molecules of H2 gas formed, we need to convert moles of NH3 and H2SO4 into moles of H2 gas and then convert it into the number of molecules.
First, let's calculate the number of moles of H2 gas that can be formed from the given amount of NH3 and H2SO4.
The balanced chemical equation for the reaction between NH3 and H2SO4 is:
2 NH3 + H2SO4 → (NH4)2SO4
From the balanced equation, we can see that 2 moles of NH3 react with 1 mole of H2SO4 to form (NH4)2SO4. It also means that 2 moles of H2 are produced. Therefore, the number of moles of H2 gas produced will be twice the number of moles of NH3 used.
Given that we have 10 moles of NH3, we can calculate the moles of H2 gas produced:
Moles of H2 = 2 * Moles of NH3
= 2 * 10
= 20 moles
Now, let's convert the moles of H2 gas into the number of molecules. To do this, we will use Avogadro's number.
Avogadro's number tells us that 1 mole of any substance contains 6.022 x 10^23 molecules.
Number of molecules of H2 = Moles of H2 * Avogadro's number
= 20 * 6.022 x 10^23
≈ 1.2044 x 10^25 molecules
Therefore, approximately 1.2044 x 10^25 molecules of H2 gas will be formed.
