Question

Calculate the mass of one atom of hydrogen helium and find its %

Answer 1

Answer:

These numbers are either in atomic mass units (amu), or in grams per mole of atoms. This means that 1 MOLE of hydrogen atoms will weigh 1.008 grams. That said, to find the mass of one ATOM, we need to convert from moles to atoms as follows: 1.008 grams/mole Hydrogen * (1 mole/6.022x1023 atoms) = 1.67 x 10-24 grams.
