Answer to Question #285182 in General Chemistry for Natao

Question

A sample of carbon dioxide occupies a volume of 3.50 liters at 125 kPa pressure. What pressure would the gas exert if the volume was decreased to 2.00 liters

Answer 1

Applying Boyle's Law;

P1V1 = P2V2

Since we are given P1 = 125kPa, V1 = 3.5L, and V2 = 2.00L.

We are to find P2

Thus, we can rearrange the equation to make P2 the subject of the formula.

Thus, P2 = P1V1/V2

Substituting for P1, V1, and V2 gives

P2 = 125kPa x 3.50L / 2.00L

= 218.75 kPa
