N2H4 is straightforward with no double or triple bonds. In the N2H4 Lewis structure the two Nitrogen (N) atoms go in the center (Hydrogen always goes on the outside). Hydrogen (H) only needs two valence electrons to have a full outer shell. In the Lewis structure for N2H4 there are a total of 14 valence electrons.

Calculation of mole from number of particles and vice – versa. Here, 2 moles of N2 molecules will have 2x2 moles of N atoms or particles. So, 4 mole of N atoms = 4 x 6.022 x 10^23 atoms of Nitogen. Hope it will be helpful.

Ammonia (NH3) can be produced by the reaction of hydrogen gas with nitrogen gas: 3H2 + N2 = 2NH3. A chemist reacts 2.00 mol H2 with excess N2. The reaction yields 0.54 mol NH3.

As one mole of H2 contains 6.022×10^23 molecules of H2. And one molecule contain 2 Hydrogen atoms. So, 1 mole of H2 will have 1.2044×10^24 atoms.

The number of moles of hydrogen will be the number of hydrogen in the chemical formula. Once you see the chemical formula is C20H24N2O2 then you know that there are 24 moles of hydrogen for every one mole of quinine.

Answer: 1 mole of anything contains 6.02 x 1023 particles. (Note that "mol" is the abbreviation for mole.) So, 4.21 mol of hydrogen gas contains 4.21 x 6.02 x 1023 = 2.53 x 1024 molecules of hydrogen.

In order to have one mole of things, let's say particles, you need to have 6.022⋅1023 particles → this is known as Avogadro's constant and acts as the definition of the mole. So, in one mole of nitrogen gas you have 6.022⋅1023 molecules of nitrogen gas, N2 .

This can be fixed by multiplying the product contacting nitrogen by 2. o The new chemical equation is N2 +H2 →2 NH3 Reactants Products Nitrogen 2 2 Hydrogen 2 6 Since NH3 is multiplied by a coefficient of 2 there are now 2 nitrogens and 6 hydrogens. The 6 hydrogens come from the 2 multiplied by the subscript of 3.
