Question

If 12.00 L of a gas is at 780.0 mmHg pressure, what is its volume at 740 mmHg?
The volume at 740 mmHg

Answer 1

Answer:

12.65 L

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

$V_2 = \frac{12 \times 780}{740} = \frac{9360}{740} \\ = 12.648648...$

We have the final answer as

12.65 L

Hope this helps you
