<h3>Further explanation</h3>The equilibrium constant is the value of the product in the equilibrium state of the substance in the right (product) divided by the substance in the left (reactant) with the exponents of each reaction coefficient
The equilibrium constant is based on the concentration (Kc) in a reaction
pA + qB -----> mC + nD
While the equilibrium constant is based on partial pressure
The value of Kp and Kc can be linked to the formula '
R = gas constant = 0.0821 L.atm / mol.K
=n = number of product coefficients-number of reactant coefficients
An equilibrium mixture: 0.750 moles of CO2 and H2, and 0.200 moles of CO and H2O
- We determine Kc (constant concentration)
- the amount of carbon monoxide to 0.300 mol
Reaction :
CO +H₂O ⇔ CO₂ + H₂
initially 0.2 0.2 0.75+x 0.75
reaction 0.1 0.1 0.1 0.1
product 0.3 0.3 0.65+x 0.65

Answer:
The answer is
<h3>1.340 × 10²⁴ sodium atoms</h3>To find the number of atoms of sodium we use the formula
N = n × L
where
n is the number of moles
N is the number of entities
L is Avogadro's constant which is
We need to find the number of moles first
The formula is
where
M is the molar mass
m is the mass
n is the number of moles
From the question
M = 22.9 g/mol
m = 51.0 g
n = 2.227 moles
So the number of sodium atoms is
We have the final answer as
<h3>1.340 × 10²⁴ sodium atoms</h3>Hope this helps you
