Density is equal to the mass of a substance divided by its volume: density = mass of substance/volume of substance Water displacement can be used to find the volume of a solid by placing the object in a known volume of water. When the object is added to water, the measured total volume increases. This final volume is equal to the volume of the initial water plus the volume of the solid object added. To determine the volume of the...

You have discovered a new virus and you decide to estimate its size by using a series of filters. There is no loss of activity when you pass suspension of your virus through a 0.3µm filter, there is a 1 log decrease in activity upon passage through a 0.1-µm filter, and there is a total loss of the remaining activity upon passage through the 0.05-µm filter. What would be your conclusions?
