Question

020 (part 1 of 3) 

Use Boyle’s law to find V2 given

P1=372 torr, V1=137 mL, P2=719 torr.

Answer in units of mL.

021 (part 2 of 3)

Use Boyle’s law to find V1 given

P1 = 0.98 atm, V2 = 572.124 mL,

P2 = 0.42 atm.

Answer in units of mL.

022 (part 3 of 3)

Use Boyle’s law to find P1 given

V1 = 2.1 ×105 mL, P2 = 137 mm Hg,

V2 = 1.6 ×103 mL.

Answer in units of mm H

Answer 1

Boyle's Law states that, at a constant temperature and a constant amount of gas, volume and pressure are related as follows:

 

P₁V₁ = P₂V₂

 

For each of these problems, you're given three of those quantities and asked to solve for the fourth. Just plug in and solve for the unknown.
