Question

If that gas produced from n=1.95 mol is funneled into a 250 mL

vessel that is capped and kept at a temperature of 80 °C, what will
be the pressure inside the vessel?

Answer 1

Answer: 226.03 atm

Step-by-step explanation:

To solve this question, you need to use the Ideal Gas Law formula [PV=nRT] or Pressure × Volume = (# of moles) × R (gas constant) × Temperature. Since you have most of the information given to you, all you have to do to solve this question is plug in your information into the formula and solve for P.

When solving questions such as this one, make sure your units line up!

• Volume should always be converted to liters (L)
• Temperature should always be converted to Kelvin (K)
• The constant you use (R) depends on the unit that your pressure should be in.

- If your pressure should be in atmospheres (atm)⇒ use 0.08206 as your constant (R)

- If your pressure should be in kilopascals (kPa)⇒ use 8.314 as your constant (R)

- If your pressure should be in millimeters of mercury (mmHg)⇒ use 62.36 as your constant (R)
