If the volume of a gas at 0.5 atm changes from 150 mL to 75 mL, what is the new pressure?
nalin [4]

Answer:

<h2>1 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're finding the new pressure

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

We have

P_2 =  \frac{0.5 \times 150}{75}  =  \frac{75}{75}  = 1 \\

We have the final answer as

<h3>1 atm </h3>

Hope this helps you
