Question

A sample of gas occupies 1.00L at 720 torr.how many liters will the gas occupy if its pressure is increased to 760 TORR with no change in temperature?

Answer 1

The sample of the gas will occupy 0.947 L.

Since there are no changes in the temperature, we use the following formula to relate both values of pressure:

`P_1.V_1=P_2.V_2`

Then, we replace the values to find the volume:

`\begin{gathered} P_1.V_1=P_2.V_2 \\ 720torr.1.00L=760torr.V_2\text{ } \\ \frac{720torr.1.00L}{760\text{torr}}=V_{2_{}} \\ 0.947L=V_2 \end{gathered}`

So, the sample of the gas will occupy 0.947 L.
