Molar Mass
The molar mass equation is given by:
M = M
r
· g · mol
1
Where:
M: molar mass, which is the mass of one mole of a substance
M
r
: relative molar mass, also called molecular weight
This equation is obtained from the following equation:
Where:
N
A
: Avogadro constant, which is N
A
= 6.0221 · 10
23
mol
1
m
u
: molar mass constant, which is m
u
= 1 g · mol
