1
Q
What does Avogadro’s Law state?
A
- equal volumes of all gases at the same temp and pressure have the same number of moles
2
Q
Define molar volume
A
Volume occupied by 1 mole of any gas at a particular temp and pressure
3
Q
What is the molar volume of a gas at standard temp and pressure (273K, 101.3kPa)?
A
22.4dm3
4
Q

A
24.0 dm3
5
Q
How do you convert from K to degrees?
A
-273
6
Q
What is equation for gas volume?
A
Number of moles x molar volume
7
Q
What is an Ideal Gas?
A
- has neglible volume
- no intermolecular forces
- collisions are elastic, there is no transfer of energy when molecules collide
8
Q
What is the Ideal Gas equation?
A
pV = nRT p=pressure, Pa V=volume, m^3 n=number of moles R= constant, 8.31 T=temp, K
