64. Solving a chemistry problem
3. Using the method of ultramicroscopy, it was calculated that there are 10 particles of gold hydrosol in a volume of 2.5 mm3. Sol concentration 0.3 g/l, gold density 19300 kg/m3, spherical particles. What is the possible error in the calculation of the average radius of these particles if their shape is assumed to be cubic?
