A litre of a gas weigh 2 gram at 300 kelvin temperature and 1 atm pressure, if the pressure is made 75 atm then at which temperature will 1 litre of the same gas weigh 1 gram? Solution=?

45000 K .

Explanation:

Given :

A liter of a gas weigh 2 gram at 300 kelvin temperature and 1 atm pressure

We need to find the temperature in which 1 litre of the same gas weigh 1 gram

in pressure 75 atm.

We know, by ideal gas equation :

Here , n is no of moles ,

Putting initial and final values and dividing them :

Hence , this is the required solution.
