Question

A sample of gas collected at 885 mm Hg occupies 266 mL. At constant temperature, what pressure does the gas exert if the volume increases to 444 mL?

Answer 1

In this question, we have volume and pressure, and the gas law that shows the relationship between these two is the Boyle's Law, which has the following formula:

P1V1 = P2V2

We have:

P1 = 885 mmHg, which is equal to 1.16 atm

V1 = 266 mL

P2 = ?

V2 = 444 mL

Now we add these values into the formula:

1.16 * 266 = 444*P2

P2 = 0.695 atm, this will be the new pressure, letter D
