Question

The pressure inside of a sealed syringe of hydrogen gas is 80.0KPa with a volume of 250 Liters. What is the pressure inside
of the syringe after the plunger is pulled back far enough to make final volume of the syringe 0.750 Liters? (assume the
temperature and amount of gas in the container are held constant)

Answer 1

Answer:

26666.67 kPa

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 are finding the new pressure

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

From the question we have

$P_2 = \frac{80000 \times 250}{0.75} = \frac{20000000}{0.75} \\ = 26666666.6666 \\ = 26666667$

We have the final answer as

26666.67 kPa

Hope this helps you
