A gas starts at a volume of 23 L and a pressure of 1.23 atm. What is the new pressure if you

Anna71 [15]

Answer:

<h2>1.89 atm</h2>

Explanation:

The new volume 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 volume

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

From the question we have

$V_2 = \frac{1.23 \times 23}{15} = \frac{28.29}{15} \\ = 1.886$

We have the final answer as

<h3>1.89 atm</h3>

Hope this helps you
