What is the pressure exerted by 32.00 g of Oxygen gas in a 20. L container at 30.00 C? Use R = 0.0821 L atm/mol k?
First, let's determine the number of mole of oxygen gas.
Then, let's convert the units of the given temperature to
Now, let's substitute all relevant values into the equation
Therefore, the pressure exerted by the oxygen gas is
Note: mols and moles are the same things; formatting issues prevent me from using the same word throughout the answer
We will use the ideal gas equation, which is as follows:
We are solving for
Now, we find the rest of the numbers to plug in
Now, we solve.
First by plugging in numbers:
Which is the same as:
Liters, moles, and Kelvin cancel out, giving us:
Now we simplify to get our answer:
The pressure is 1.2 atm.
This is an ideal gas law problem. The equation is:
You have been given the mass of
You have been given temperature in degrees Celsius, but gas problems require the temperature to be in Kelvins. Convert
Rearrange the equation to isolate
