A student measured the mass of 10.0 mL of unknown polymer to be 13.2 g at 28oC. she then used a viscometer to measure the flow times for water and an unknown polymer and found them to be 10.6 s and 15.4 s respectively. given the density of water at 28oC is 0.999 g/cm3 and the viscosity of water at 28oC is 0.7978 cP, find the viscosity of the unknown polymer at the same temperature.
Homework Answers
The viscosity and flow time of a particular solution are directly proportional to each other at a fixed temperature .
The viscosity of the unknown polymer at 28°C is 1.1591 centipoise (cP).
The detail calculation is shown below.

A student is determining the density of an unknown metal with a mass of 56.5 g. The student partially fills a graduated cylinder with water and measures the volume of the water by itself as 54.8 mL. The student then adds the metal to the water and measures the new volume as 87.3 mL. What is the density, in g/mL, of the metal?

Post Lab #1 A student was assigned the task of determining the molar mass of an unknown gas. The student measured the mass of a sealed 843 mL rigid flask that contained dry air. The student then flushed the flask with the unknown gas, resealed it, and measured the mass again. Both the air and the unknown gas were at 23.0°C and 750. torr. The data for the experiment are shown in the table below. Volume of sealed flask 843...
