If 765 mL of a gas at 2.78 atm, has the volume Change to 2.47 L , What is the pressure of the
vampirchik [111]

Answer:

<h2>0.87 atm </h2>

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

<h3>0.87 atm</h3>

Hope this helps you
