Question

If 765 mL of a gas at 2.78 atm, has the volume Change to 2.47 L , What is the pressure of the

gas in atm?

Answer 1

0.87 atm

Step-by-step explanation:

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

`P_1V_1 = P_2V_2`

Since we are finding the new pressure

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

From the question

2.47 L = 2470 mL

We have

`P_2 = (765 * 2.78)/(2470) = (2142)/(2470) \\ = 0.867206...`

We have the final answer as

0.87 atm

Hope this helps you
