Product description
4. In order to determine the molecular weight of rubber, its osmotic pressure was measured in benzene (1) and in mixed solvents: benzene - isoamyl alcohol (2), benzene - methyl alcohol, benzene - hexyl alcohol (4). Based on the table data, calculate the molecular weight of rubber and answer the question - does the limiting value of the reduced osmotic pressure depend on the type of solvent. Experiment temperature 27.5 C
