Question

9A. A sample of hydrogen at 1.56 atm had it's pressure decreased to 0.73

atm producing a new volume of 751 mL. What was its original volume? *
7 points
351 mL
1,600 mL
273 mL
0.0015 ml

Answer 1

351.43 mL

Step-by-step explanation:

The original 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 original volume

`V_1 = (P_2V_2)/(P_1) \\`

From the question we have

`V_1 = (0.73 * 751)/(1.56) = (548.23)/(1.56) \\ = 351.429487...`

We have the final answer as

351.43 mL

Hope this helps you
