Question

Assume that you have a sample of a gas. You know the volume, the temperature and the number of moles of the sample. Which of the following laws would you use if you wanted to calculate the pressure of the sample?

1) Boyle's law
2) Charles's law
3) Law of Combining Volumes
4) Ideal Gas Law

Answer 1

To calculate the pressure of a gas sample given the volume, temperature, and number of moles, you would use the Ideal Gas Law.

Step-by-step explanation:

If you want to calculate the pressure of a gas sample given the volume, temperature, and number of moles, you would use the Ideal Gas Law. The Ideal Gas Law relates the pressure, volume, temperature, and number of moles of a gas. It can be expressed as:

PV = nRT

• P is the pressure of the gas
• V is the volume of the gas
• n is the number of moles of the gas
• R is the ideal gas constant
• T is the temperature of the gas in Kelvin
