Agas in a container with a fixed volume was originally at a pressure of 317kpa and a temperature of 154k. what is the new pressure in atm if the temperature is increased to 235k

The answer is: 4.77atm

Since there's a fixed volume, we can use the the Gay-Lussac's Law which stablish a relation between the pressure and the temperature:

P is the volume of the gas

t is the temperature of the gas

k is the proportionality constant

We also have the following equation:

Where:

We are asked to find the pressure in atm, so we must convert 483.73kPa to atm:

Then,

Have a nice day!

nacl is added to the aqueous of what? ? in order to get a proper answer you have to specify the exact composition of the aqueous solution.
