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.
Courtney’s in minerals can vary due to impurities but is usually diagnostic we determine the relative hardness of minerals using a scale diversity bye mineralogists Freidrich Mohs The scale assigned hardness Tuten common index minerals and is based up on the ability of one mineral to scratch another
Li2O + H2O → 2LiOH
This is the answer

Given an equilibrium constant value of 7.2 x 10-4 it is false to say that the reaction proceeds essentially to completion.
<h3>What is the equilibrium constant?</h3>
In a reaction, we can judge using the value of the equilibrium constant weather or not the reaction moves on to completion. If the reaction moves up to completion, it the follows that the value of the equilibrium constant ought to be large.
On the other hand, when we have a case that the equilibrium constant is small and is not so large, then the reaction does not proceed essentially to completion.
