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?

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:
[tex]P_1.V_1=P_2.V_2[/tex]Then, we replace the values to find the volume:
[tex]\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}[/tex]So, the sample of the gas will occupy 0.947 L.
