Question

G atomic mass of h is 1.008 g calculate the mass of one h atom in g

Answer 1

Answer:

One mole of a gas at STP contains 6.022×10²³ atoms. Hydrogen's atomic weight is 1. This means that 1 mol of hydrogen atoms (6,023*10^23 atoms) weighs 1 gram. Dividing the two, 1 hydrogen atom weighs 1.66*10^-24 grams.

Answer 2

Explanation:

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.
