Answer: 0.245 moles of oxygen must be placed in the container to exert the given pressure at the given temperature. The Ideal Gas Law equation gives the relationship among the pressure, volume, temperature, and moles of gas.
Further Explanation:
The Ideal Gas Equation is:
where:
P - pressure (in atm)
V - volume (in L)
n - amount of gas (in moles)
R - universal gas constant
T - temperature (in K)
In the problem, we are given the values:
P = 2.00 atm (3 significant figures)
V = 3.00 L (3 significant figures)
n = ?
T = 25.0 degrees Celsius (3 significant figures)
We need to convert the temperature to Kelvin before we can use the Ideal Gas Equation. The formula to convert from degree Celsius to Kelvin is:
Therefore, for this problem,
Solving for n using the Ideal Gas Equation:
The least number of significant figures is 3, therefore, the final answer must have only 3 significant figures.

The equilibrium constant for the reaction
N₂O₄(g)⇌2NO₂ at 2°C is Kc = 2.0
If each yellow sphere represents 1 mol of N₂O₄(g) and each gray sphere 1 mol of NO₂ which of the following 1.0 L containers represents the equilibrium mixture at 2°C?
The image is attached below.
<u>Answer:</u> The system which represents the equilibrium having value of is system (b)
<u>Explanation:</u>
Equilibrium constant in terms of concentration is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as
For a general chemical reaction:
The expression for is written as:
For the given chemical equation:
The expression of for above equation follows:
.......(1)
We are given:
Volume of the container = 1.0 L
Value of = 2.0
Molarity of the substance is calculated by using the equation:
For the given images:
- <u>For a:</u>
Number of Gray spheres = 8 moles
Number of yellow spheres = 4 moles
Putting values in expression 1, we get:
- <u>For b:</u>
Number of Gray spheres = 4 moles
Number of yellow spheres = 8 moles
Putting values in expression 1, we get:
- <u>For c:</u>
Number of Gray spheres = 6 moles
Number of yellow spheres = 6 moles
Putting values in expression 1, we get:
- <u>For d:</u>
Number of Gray spheres = 2 moles
Number of yellow spheres = 8 moles
Putting values in expression 1, we get:
Hence, the system which represents the equilibrium having value of is system (b)
