Answer:
797.34 moles of H₂
Explanation:
From the question given above, the following data were obtained:
Number of molecules of H₂ = 4.8×10²⁶ molecules
Number of mole of H₂ =?
From Avogadro's hypothesis,
1 mole of H₂ = 6.02×10²³ molecules
With the above information, we can determine the number of mole of H₂ that contains 4.8×10²⁶ molecules as follow:
6.02×10²³ molecules = 1 mole of H₂
Therefore,
4.8×10²⁶ molecules = 4.8×10²⁶ / 6.02×10²³
4.8×10²⁶ molecules = 797.34 moles
Thus, 797.34 moles of H₂ contains 4.8×10²⁶ molecules.
