Membrane osmometry, a colligative-property method, directly gives the
A
degree of cross-linking
B
weight-average molar mass
C
number-average molar mass
D
polydispersity index
Answer: C
Colligative properties depend on the number of solute particles, so osmotic pressure measurements give the number-average molar mass
M
n
