Question

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

Answer 1

Answer:

1 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'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

1 atm

Hope this helps you
