WebAug 28, 2024 · Calculate the M W for a polymer sample comprising of 9 moles of polymer molecules having molecular weight of 30.000 g/mol and 5 moles of polymer molecules having molecular weight of 50.000 g/mol. Answer: Z-average molecular weight (M Z) The Z-average molecular weight (M z) is measured in some sedimentation equilibrium … Molar masses are almost never measured directly. They may be calculated from standard atomic masses, and are often listed in chemical catalogues and on safety data sheets (SDS). Molar masses typically vary between: 1–238 g/mol for atoms of naturally occurring elements; 10–1000 g/mol for simple chemical compounds; 1000–5000000 g/mol for polymers, proteins, DNA fragments, etc.

WebSituational Problems 1. Pepsinogen (an inactive form of the enzyme) that forms in the main cells of the stomach has a molecular weight of 42,000 D. In the gastric juice, the pepsinogen turns into the active enzyme pepsin, while its molecular weight decreases to 35,000 D. Explain the mechanism of regulation of enzyme activity. WebMar 16, 2024 · Raman spectroscopy is an alternative way to get information about the infrared transitions within a molecule. In order for a vibrational transition to be Raman active, the molecule must undergo a change in polarizability during the vibration. Polarizability refers to the ease of distorting electrons from their original position.
