Question

A 75.0-ml sample of oxygen has a pressure of 1.50 atm. What will be the new

volume, in milliliters, if the pressure of the sample becomes 4.50 atm (T, n
constant)? (Show calculations.)

Answer 1

The answer is 25 mL

Step-by-step explanation:

The new volume can be found by using the formula for Boyle's law which is

`P_1V_1 = P_2V_2`

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

Since we are finding the new volume

`V_2 = (P_1V_1)/(P_2) \\`

From the question we have

`V_2 = (75 * 1.5)/(4.5) = (112.5)/(4.5) \\`

We have the final answer as

25 mL

Hope this helps you
