Question

A 7.50 L sample of gas collected in the upper atmosphere at a pressure of 18.3 torr is compressed into a 170.0 mL container at the same temperature. What is the new pressure?

Answer 1

The answer is 807.35 torr

Step-by-step explanation:

In order to find the new pressure we use 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

From the question

P1 = 18.3 torr

V1 = 7.5 L = 7500 mL

V2 = 170 mL

Since we are finding the final pressure

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

We have

`P_2 = (18.3 * 7500)/(170) \\ = 807.3529411...`

We have the final answer as

807.35 torr
