# If #2.4*10^5# #L# of gas is at #180# #mmHg#, what is the pressure when the gas is compressed to #1.8*10^3# #L# at constant temperature?

##### 1 Answer

#### Answer:

The new pressure is

#### Explanation:

Let's start off with identifying our known and unknown variables.

The first volume we have is

We can obtain the answer using Boyle's Law which shows that there is an inverse relationship between pressure and volume as long as the temperature and number of moles remain constant.

The equation we use is

where the numbers 1 and 2 represent the first and second conditions. All we have to do is rearrange the equation to solve for the pressure.

We do this by dividing both sides by

Now all we do is plug and chug!
