Examine the importance and impact of isomerism in
industry – research case studies in order to consider the
formation of different isomers during manufacture, how
their presence may influence the industrial process, the
differences in properties that they might have, and the
possible consequences of ignoring the presence of
isomerism.

calculate the vapour pressure of a solvent above a solution containing 83.99g of solute of molecular mass 195 .62per 1000g of water 20°c is 17.53 mmhg
In the Tools menu, check Width to enable a ruler below the box. Drag the handle on the left and adjust the length of the box to 5 nm. (Because no other dimensions of the box change, its length can be used as a substitute for volume.) Pump the pump handle once fully. This should add 40 to 50 gas molecules to the container. The pressure gauge will fluctuate a little bit, so watch it for a minute to estimate an average value. Record the pressure in the table.
In the Constant Parameter menu, select Temperature. Then drag the handle of the box to change its length to each of the other values in the data table. Record the pressure for each length.
