Product description
23 The density of silver is 10.5 g / cm3. The sol contains in 1 dm3 1 mg of silver and is diluted 100 times. The total number of particles in the field of view of the ultramicroscope in the calculation turned out to be 10. The field of view is 1⋅10-8 m2 and the depth of the beam is 1⋅10-5 m. Assuming that the silver particles are spherical and have the same density as solid silver, calculate their average radius.
