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

Answer 1

Answer:

0.87 atm

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

$P_2 = \frac{P_1V_1}{V_2}$

From the question

2.47 L = 2470 mL

We have

$P_2 = \frac{765 \times 2.78}{2470} = \frac{2142}{2470} \\ = 0.867206...$

We have the final answer as

0.87 atm

Hope this helps you
