600. ml of a gas at 50.0 kPa is compressed, at constant temperature, until its volume becomes 200. ml. What is the new pressure
Flura [38]

Answer:

<h3>The answer is 150 kPa</h3>

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 we have

P_2 =  \frac{600 \times 50000}{200}  =  \frac{30000000}{200}  \\  = 150000

We have the final answer as

<h3>150 kPa</h3>

Hope this helps you
