# 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?

##### 1 Answer

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
