The answer is 1 only. Please explain how do we solve this question.

(mod edit, change title to something more useful)

The answer is 1 only. Please explain how do we solve this question.

• p = ρRT/N
• pV = MRT
• pV = cRT/M

where p = pressure, ρ = density, V = volume; M = molar mass; c = concentration; R = gas constant; T = temperature.

What forms of the ideal gas law do you know?

I belive there is a rule saying you have to show some work before ppl help you.
Anyway, write ideal gas equation and then compare it with given answers. You should see what is missing and what more you have in given answers. Then, try to derive the missing in ideal gas equation using given variables in your answers.
I hope I explained it well, im not native english speaker

As the title explains...write down the ideal gas equation PV= nRT, where P stands for pressure, V for volume, n for number of moles(do you the formula for n?), R is gas constant, T is temperature...!

Try to solve it, it's an easy question, if you are not able to do it, then show you have attempted it.
