There poisonous gas that needs to be removed from a room. The room is at 1 atm and 270 C. A machine can remove the gas at 32 mL/minute. How long will it take to remove all the gas?

1391 minutes

Explanation:

To solve the problem, we need to find first the volume of gas present in the room.

We can do it by using the equation of state for an ideal gas:

where

p = 1 atm is the pressure

V is the volume

n = 1 mol is the number of moles (not given in the problem, so we assume its value)

is the gas constant

is the temperature

Solving for V,

So, there are 44.5 L of gas in the room.

The gas can be removed at a rate of

Therefore, the time it takes is:

the answers would be

the first one and the second one
