Molar Volume and Ideal Gases

Question 1

What did Avogadro hypothesise about ideal conditions of temp, pressure and volume of gas and what does that mean? (molar volume)

Answer 1

ideal condtions of temp, pressure and volume of gas contain an equal number of gas particles.
It means that one mole of any gas at the same temperature and pressure will have a specific volume. This is known as molar volume.

Question 2

What are the two standard systems that scientists refer to?

Answer 2

STP (standard temperature and pressure) and SLC (standard laboratory conditions)

Question 3

What equation is the relationship between moles and volume?

Answer 3

n = V/Vm

Question 4

At STP, what does equation n = V/Vm (hint: refer to formula sheet)

Answer 4

n = V/22.4

Question 5

At SLC, what does equation n=V/Vm (hint: refer to formula sheet)

Answer 5

n = V/24.5

Question 6

What is the ideal gas equation?

Answer 6

PV = nRT

P - pressure (kPA)
V - volume (L)
n - number of moles
T - temperature (K)
R - 8.314 (Jmol^-1K^-1)
