Answer: 6.02 × molecules of hydrogen are in the container. The Ideal Gas Law equation gives the relationship among the pressure, volume, temperature, and moles of gas. Once the moles of gas is determined, we use Avogadro's number, 6.022 × to get he number of molecules.
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 = 1 atm
V = 224 mL = 0.224 L (3 significant figures)
n = ?
T = 0 degrees Celsius
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:
Now that we know the number of moles of hydrogen gas, we can determine how many molecules there are:
