DF - Gas volumes

Question 1

What volume does 1 mole of any gas have at room temperature and pressure (RTP)?

Answer 1

24dm^3

Question 2

What are the values for RTP?

Answer 2

298K (25 degrees celsius) and 100kPa.

Question 3

What is the ideal gas equation?

Answer 3

pV=nRT

Question 4

What do the components of the ideal gas equation stand for?

pV=nRT

Answer 4

p= pressure (Pa)
V= volume (m^3)
n= number of moles
R= 8.314 J K^-1 mol^-1 (gas constant)
T= Temperature (K)

Question 5

What does the ideal gas equation let you find out?

Answer 5

The number of moles in a certain volume at any temperature and pressure.

Question 6

How do you convert from celsius to kelvin?

Answer 6

+273

Question 7

What piece of apparatus can be used to measure gas volume?

Answer 7

A gas syringe attached to the opening of a reaction vessel lets you measure how much gas is produced in a reaction.

Question 8

How can you tell when measuring gas volumes using a gas syringe, that the reaction has ended?

Answer 8

There will be no further change in gas volume.

Question 9

What can really vigorous reactions do to a gas syringe?

Answer 9

Blow the plunger out so you have to be careful.
