Answer: 5.00 x 10^23 atoms
Explanation:
Based on Avogadro's law:
1 mole of any substance has 6.02 x 10^23 atoms
So, 1 mole of Iron = 6.02 x 10^23 atoms
0.83 moles of Iron = Z atoms
To get the value of Z, cross multiply:
Z atoms x 1mole = (6.02 x 10^23 x 0.83)
Z = 5.00 x 10^23 atoms
Thus, there are 5.00 x 10^23 atoms of iron.
<u>Answer:</u> The equilibrium constant for the given reaction is 1.33
<u>Explanation:</u>
We are given:
Equilibrium concentration of ammonia = 2 M
Equilibrium concentration of nitrogen gas = 3 M
Equilibrium concentration of hydrogen gas = 1 M
For the given chemical equation:

The expression of
for above equation follows:
![K_{eq}=\frac{[NH_3]^2}{[N_2][H_3]^3}](https://tex.z-dn.net/?f=K_%7Beq%7D%3D%5Cfrac%7B%5BNH_3%5D%5E2%7D%7B%5BN_2%5D%5BH_3%5D%5E3%7D)
Putting values in above equation, we get:

Hence, the equilibrium constant for the given reaction is 1.33
Just do 6 x 2.2
6 x 2.2 = 13.2
