The new pressure is 75.51 mmHg if a sample of carbon monoxide gas is contained in a 345 mL vessel at a temperature of 25 °C. and a pressure of 985 mmHg and the gas is allowed to expand to a new volume of 4.50 litres at a constant temperature.

What is a gas law?

The gas laws consist of three primary laws: Charles' Law, Boyle's Law and Avogadro's Law (all of which will later combine into the General Gas Equation and Ideal Gas Law).

The pressure on the gas changes, while the temperature remains constant, and we want to find the new volume. So, we will use Boyle's Law, which states there is an inverse relationship between the pressure on a gas and the volume of the gas. The formula is:

[tex]P_1V_1=P_2V_2[/tex]

[tex]P_1 = 985 mm Hg[/tex]

[tex]V_1 = 345 mL[/tex] =

[tex]P_2 = ?[/tex]

[tex]V_2 = 4.50 liters[/tex]

The pressure of the gas is originally 985 mm Hg and the volume is 345 mL.

We are solving for the new volume, so we must isolate the variable V₂.

Now putting all the values in the equation:

[tex]P_1V_1=P_2V_2[/tex]

[tex]985 X 0.345 L=P_2 X 4.50[/tex]

[tex]P_2[/tex] = 75.51 mmHg

Hence, the new pressure is 75.51 mmHg.
