Answer: Concentration of N₂ is 4.8. M.
Explanation: is a constant of equilibrium and it is dependent of the concentrations of the reactants and the products of a balanced reaction. For
N2(g) + 2 O2(g) ⇄ 2 NO2(g)
=
From the question concentration of NO2 is twice of O2:
[NO2] = 2[O2]
Substituting this into :
=
8.3. =
[N2] =
[N2] =
[N2] = 4.8.
The concentration of N2 in the equilibrium is [N2] = 4.8.M.
Answer:
Explanation:
Hello,
In this case, the first step is to compute the molar mass of carbon dioxide as shown below, considering it has one carbon atom and two oxygen atoms:
It is important to notice it is the mass in one mole of such compound. Afterwards, we need to use the Avogadro's number to compute the how many moles are in the given molecules of carbon dioxide as shown below:
Finally, the mass by using the molar mass:
Best regards.
