    Hello ishan1992. Welcome to the forum.

    To get help with your homework you need to show that you have made some attempt to solve the problem yourself. We are not supposed to just do your homework for you. If you can show that you made an attempt, or ask for help on a particular place that you are stuck, then we will be glad to help. But we can't just answer your homework questions for you.

    I will give you one hint here. Do you know the ideal gas law?
