# Answer on Inorganic Chemistry Question for Shay

Question #31461

A 2.50L sample of carbon monoxide gas has a pressure of 835mmHg. Assuming the temperature remains constant, what is the final pressure if the volume is changed to 6.35L?

Expert's answer

Carbon monoxide gas that has a pressure of 835 mm Hg will be 908.38764 Pa.

Using the Ideal Gas equation:

PV = nRT, from this:

Where:

P - pressure

V - volume

At the T - const:

P

P

P

Answer: 357.63 Pa

Using the Ideal Gas equation:

PV = nRT, from this:

Where:

P - pressure

V - volume

At the T - const:

P

_{1}V_{1}= P_{2}V_{2}, from this equiation:P

_{2}= P_{1}*V_{1}/(V_{2})P

_{2}= 908.38764 Pa x 2.5 L/(6.35 L)P

_{2}= 2270.95/6.35P

_{2}= 357.63 PaAnswer: 357.63 Pa
