Answer:
why can't u leave me........
1L of 0.5M HCl contains 0.5mol of HCl which can react.
This can be found by the fact that
molarity is defined as the number of moles of a substance per Liter of solution. That means that 0.5M of HCl can be thought of as 0.5moles of HCl per liter of solution.
In general to find the number of moles of substance in a solution using the molarity all you do is multiply the molarity by the volume of the solution (in liters).
I hope this helps. Let me know if anything is unclear.
The answer is 73.71%. Hope I helped plus mark as brailiest ^-^
<u>Answer:</u> 6 moles of
will be decomposed.
<u>Explanation:</u>
We are given:
Moles of oxygen gas produced = 9 moles
The chemical equation for the decomposition of
follows:

By the stoichiometry of the reaction:
If 3 moles of oxygen gas is produced by 2 moles of
So, 9 moles of oxygen gas will be produced by =
of 
Hence, 6 moles of
will be decomposed.
