18 янв. 2017 г. · Mass of one mole hydrogen molecules (6.023×10^23) = 2 grams. Mass of one H2 molecule =2/(6.023×10^23) = 0.33×10^-23 grams. What is the mass in grams of 1 mole of hydrogen gas? What is the molecular weight of hydrogen? Другие результаты с сайта www.quora.com

The mass of hydrogen molecule is 2.016 amu. Therefore the number of hydrogen molecules in 4.032gm of hydrogen will be: 6.023×1021; 2×6.023×1023 ...

29 окт. 2023 г. · The mass of an H2 molecule in grams is approximately 2.016 amu * (1.66053906660 x 10^-24 grams/1 amu) = 3.35 x 10^-24 grams.

1 mole of H2 contains 6.022×1023 hydrogen molecules. Thus, 3.01 × 1023 molecules are there in one gram of hydrogen. Ace your General Science and Chemistry ...

22 июл. 2019 г. · 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 сент. 2021 г. · Hydrogen (1 mole/6.022 x 1023 atoms) = 1.67 x 10-24 grams. The mass or weight of a hydrogen atom would be 1.68 grams (1.008 x 1.67).

The mass of a hydrogen molecule is 2.016 amu. Therefor the number of hydrogen molecules in 4.032gm of hydrogen will be: A. \[6.023\times {{10}^{21}}\]

5 авг. 2017 г. · Well, to a first approximation, one mole of hydrogen atoms has a mass of 1⋅g ...........Agreed? Explanation: And thus to find the mass of 1 ...

Atomic mass = No. of protons + No. of neutrons. So, atomic mass of hydrogen (H) = 1 + 0 = 1 u. Molecular formula of hydrogen is (H2) so molecular mass will ...
