The pressure in a 5.75 L container of 48.0 g of bromine gas at 100.0°C is ....... What is the pressure in atm?
Alright, so we want to use the ideal gas law to solve for Pressure.
Pressure is unknown
Volume is 5.75 L
n is the number of mols, which we must solve for
R is the gas constant, 0.082
T is the temperature in K, which we must solve for
Solving for n: As you may recall, the formula for moles is
Using this, we solve that n=0.300
Solving for T in K: We are given that the temperature is 100.0ºC. The formula for converting ºC-->K is:
Therefore, the temperature is 373.2 K
Now, we can plug this all into the Ideal Gas Law to solve for Pressure in atm
