N₂O₄ (g) ⇌ 2 NO₂ (g)

Kc = [ NO₂ ]² / [ N₂O₄ ]

4.2 =  [ 0.785 ] [ N₂O₄ ]

[ N₂O₄ ] = 4.2 / 0.785

[N₂O₄ ] = 5.350 M

hope this helps!

Alina [70]

Answer:

<h2>0.059 moles</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L} \\

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

n =  \frac{3.55 \times  {10}^{22} }{6.02 \times  {10}^{23} }  \\  = 0.05897...

We have the final answer as

<h3>0.059 moles</h3>

Hope this helps you
