M | kg/mol |
It measures as ratio of substance mass
m to amount of substance
\nu:
M = \frac{m}{\nu} |
It relates to molecular mass
m_u and Avogadro constant
N_A as:
M = m_u \cdot N_A |
The molar mass of a mixture is:
M = \sum_k M_k \cdot x_k |
where
M_k | molar mass of the k-th mixture component |
x_k | mole fraction of the k-th mixture component |
