Decide which molecules in the simulation will represent the substances from the actual reaction. Include a strategy to deal with the difference in structure between the actual reaction N2 + 3H2 = 2NH3 and the simulated reaction. Not all molecules need to be used.

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
