Answer Expert Verified In ammonium carbonate there are two nitrogen atoms (because two ammonium cations), eight hydrogen atoms (because two ammonium cations), one carbon atom and three oxygen atoms: 2 · 1N + 2 · 4H + 1C + 3O = 14 atoms.

There are 1(Cu) + 1(S) + 4(O) + 5(2(H) + 1(O)) = 6 + 5x3 = 21 atoms per molecule. There are Avagadro's number of Molecules / Mole. There are The molecular weight grams in a mole W gram/Mole.

The number of moles in 27.6g ammonia is 27.6 ÷ 17 = 1.62 mol. A mole is 6.02 × 10²³, so the number of hydrogen atoms in a 1.62 moles of ammonia is 1.62 × 6.02 × 10²³ × 3 = 2.93 × 10²⁴ atoms.

Within one molecule of NH3, we have one nitrogen atom and three hydrogen atoms, which gives us a total of four atoms within one molecule of NH3. So, there's a total of four times an Avogadro's number of atoms within one mole of NH3.

Ammonia, formed of 3 hydrogen atoms and a nitrogen atom, has an atomic weight of 17g/mol. (Actually 17.031g/mol if we're being picky.) This means that 17g of ammonia is one mole of ammonia. The number of molecules in a single mole of any compound is given by Avoadro's constant, which is 6.023x10^23.

of it will have 8*Avogadro's number of atoms. 5 mol. of it will have 5*8*Avogadro's number of atoms. = 2.4092 * 10^25 atoms.

For example, 10 molecules of nitrogen would react with 30 molecules of hydrogen to produce 20 molecules of ammonia. The most useful quantity for counting particles is the mole.

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.

1mol contain 6.023*10^23 atoms. so 4.25 moles contain 4.25*6.023*10^23 atoms. so the answer is 2.56*10^24 atoms. thank you.

Ammonia's molecular formula is NH3. Its molar mass is 17.0306g.
177710
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.
