A drop of water is 0.05 mL of water, so its mass would be 0.05 grams. Atomic mass- 1.01 Formula- grams × (6.02 × 1023) / atomic mass = number of atoms 1.00 grams H × (6.02 × 1023) / 1.01 grams = 5.96 × 1023 atoms of hydrogen What is the conflict of the story sinigang by marby villaceran? If it is assumed there are 6x10^23 atoms in a mole, and 1 mole is the molecular weight of the H2O molecule (3 atoms). If the atomic mass unit is 1 gram of hydrogen, the number of atoms would be about 15 to 22. Hydrogen: 6.02 x 10^23 molecules x 3 atoms per molecule = 1.806x10^24 atoms Because the molecular mass of Hydrogen is 1gram/mole, there is 1 mole of hydrogen in 1 gram of hydrogen atoms.For every mole, there are 6.02*10^23 atoms so in 1 gram of hydrogen there are 6.02*10^23 hydrogen atoms (in scientific notation) this is equal to 602000000000000000000000 hydrogen atoms.
