Beyond the Answer
To find the number of moles of oxygen gas, first, we need to calculate the partial pressure of the oxygen gas. The total pressure of the gas collected over water is given as 843 mmHg, and we need to subtract the vapor pressure of water at
:
Next, we can use the Ideal Gas Law:
Where:
-
is the pressure in atm (so we convert mmHg to atm: ) -
is the volume in liters (675 mL = 0.675 L) -
is the number of moles -
is the gas constant -
is the temperature in Kelvin (convert Celsius to Kelvin: )
Plugging in the values:
Now, solving for
:
Thus, the number of moles of oxygen gas is approximately
