Question

A laboratory bottle of helium gas occupies a volume of 2.0 L at 760 mm Hg. Calculate the new pressure if the

Answer 1

Answer:

844.4 mmHg

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

$P_2 = \frac{2 \times 760}{1.8} = \frac{1520}{1.8} \\ = 844.4444...$

We have the final answer as

844.4 mmHg
