Question

a gas measured a volume 100 mL under pressure of 740 mmHg. What would the volume be under a pressure of 780 mmHg with constant temperature

Answer 1

94.87 mL

Step-by-step 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're finding the new volume

`V_2 = (P_1V_1)/(P_2) \\`

We have

`V_2 = (100 * 740)/(780) = (74000)/(780) \\ = 94.8717...`

We have the final answer as

94.87 mL

Hope this helps you
