6.02 x 1023 protons
|
Detailed explanation-1: -One mole of any substance contains 6.02 X 1023 units of that substance. Equally important is the fact that one mole of a substance has a mass in grams numerically equal to the formula weight of that substance.
Detailed explanation-2: -The Avogadro Constant is used to state the number of atoms or molecules in a mole of a substance. The Avogadro Constant is normally written in standard form. 6.02x1023 = 602, 000, 000, 000, 000, 000, 000, 000 correct to 3 Significant Figures.
Detailed explanation-3: -An atom of hydrogen contains one electron and one proton. No neutron is present. Thus, the number of neutrons in one mole of hydrogen is 0.
Detailed explanation-4: -It represents the number of atoms in one gram atom of an element or the number of molecules in one gram mole of a compound. If we divide the atomic mass of an element by actual mass of its atom, the value is 6.022×1023.
