A gas has a pressure of 2.67 atm and occupies a volume of 6.8 L. If the gas is compressed to a volume of 1.2 L, what will its pressure be, assuming constant temperature? Answer in units of atm.

Answer 1

To solve this problem, we can use Boyle's Law. Temperature is constant. Here is Boyle's Law:

P₁V₁ = P₂V₂

We know P₁ and we know V₁. We also know V₂. We are looking to figure out P₂.

So let's rearrange the variables in that equation.

P₂ = P₁V₁ / V₂

Now plug in the known variables.

P2 = (2.67 atm) (6.8 L) / 1.2 L = 15.13 = 15 atm

We used significant figures in the final answer.
