Web29. 1,29 x 10²⁴ hydrogen atoms in HF Answer: We know that, 1 mole of any substance contain 6.022 X 10^23 atoms/molecules. Thus, 2.14 moles are present in 1.29x10^24 hydrogen atoms in HF. 30. what is the compound name of hf. Answer: Hydrogen Fluoride. Explanation: Hydrogen fluoride is a chemical compound that contains fluorine. WebThe smallest representative unit of any chemical element is a single atom, which is always an extremely small particle. In chemistry we rarely deal with individual or small groups of atoms. We usually deal with molar quantities of atoms, in which one mole is equal to a collection of Avogadro's Number of atoms, 6.022×1023 mol−1 6.022 × 10 23 ...
