A mass of 14.71 g of K2Cr2O7 was weighed out, dissolved in deionized water, the volume made up to 250 cm3 in a volumetric flask and the mixture shaken. Calculate the concentration of this potassium dichromate(VI) solution, in mol dm–3. Use the Periodic Table as a source of data. (2...
(CAM) software. Three dimensional (3D) models can be rendered to produce photo-realistic representations, or can be animated to produce moving views of products and components as they would appear in service. Additionally, models can be used to analyse features such as mass, volume and ...
