WebNov 10, 2016 · In order to find out how many atoms we have in a certain amount of a sample, we have to use the Avogadro constant: the number of atoms in one mole, N A, is equal to 6.02 ×1023. In order to work out how many moles we have in our sample, we can use the formula n (moles) = m (mass) Mr (molar mass). n = 10 80 = 0.125. N A = 0.125 × … WebNov 8, 2024 · The formula mass of ammonia is 14 + 1 × 3 = 17. 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 × 10² atoms. I hope it helps you.
