Solution
Molarity shows the number of moles of solute in every 1 liter of solution.
Solution A : 0.5 moles : 2 L solution = 0.25 M
Solution B : 1 moles : 3 L solution = 0.33 M
Solution C : 1.5 moles : 4 L solution = 0.375 M
Answer: The pressure inside the cylinder will be 1.5 atm. The pressure can be calculated using the Ideal Gas Equation which relates the pressure, volume, temperature, and amount of gas to each other.
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 = ?
V = 10.0 L (3 significant figures)
n = 0.60 moles ( 2 significant figures)
T = 35.0 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 P using the Ideal Gas Equation:
The least number of significant figures is 2, therefore, the final answer must have only 2 significant figures.
