Question

(PLS HELP ASAP <3)

Answer 1

Answer:

675 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're finding the new pressure

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

We have

$P_2 = \frac{900 \times 600}{800} = \frac{540000}{800} \\ = 675$

We have the final answer as

675 mmHg

Hope this helps you
