Answer: 0.294 mol of present in the reaction vessel.
Explanation:
Initial moles of = 0.682 mole
Initial moles of = 0.440 mole
Volume of container = 2.00 L
Initial concentration of
Initial concentration of
equilibrium concentration of
The given balanced equilibrium reaction is,
Initial conc. 0.341 M 0.220 M 0 M
At eqm. conc. (0.341-x) M (0.220-x) M (2x) M
The expression for equilibrium constant for this reaction will be,
we are given : (0.341-x) = 0.268 M
x= 0.073 M
Thus equilibrium concentration of = (0.220-x) M = (0.220-0.073) M = 0.147 M
Thus there are 0.294 mol of present in the reaction vessel.
Answer:
<h2>2.54 moles</h2>Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>2.54 moles</h3>Hope this helps you
