the pressure of a has is 1.0 atm and it occupies a volume of 2.50 L. What will he the new volume of this has if the pressure is
NikAS [45]

Answer:

<h2>1.25 L</h2>

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 are finding the new volume

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

From the question we have

V_2 =  \frac{1 \times 2.5}{2}  =  \frac{2.5}{2}  \\

We have the final answer as

<h3>1.25 L</h3>

Hope this helps you
