What is a molar mass

The mass of one mole of a substance

Equation to find the number of atoms of molecules in a substance

(Number of moles in substance) X Avogadros constant

n X NA

What is avogadros constant

6.02 X 10^23

Assumptions made for kinetic theory of matter for an ideal gas

1-has contains large numbers of atoms or molecules moving in random directions at random speeds

2-atoms/molecules occupy negligible volume compared to volume of gas

3-atoms/molecules collide perfectly elastically with each other and the container

4-time during collisions is negligible compared to time between collisions

5-electrostatic forces of the atoms/molecules are negligible except for during collisions

Boules law

Pressure is inversely proportional to the volume provided the temperature and mass remain constant

Pressure law

Pressure is directly proportional to temperature provided the volume and mass remain constant

Charles’s law

Volume is directly proportional to the temperature provided pressure and mass remain constant

Ideal gas equation

PV=nRT P-pressure V-volume T-absolute temperature n-number if moles of gas R-molar has constant

What is the value and meaning of R

R is the molar has constant
