how many molecules of carbon tetrachloride are there in 80g of ccl4 sample

how many molecules of carbon tetrachloride are there in 80g of ccl4 sample

Solutions

Expert Solution

no of molecules = no of moles * 6.023*10^23

gram molar mass of CCl4   = 154g/mole

weight of CCl4                   = 80g

no of molecules = no of moles * 6.023*10^23

                             = ( W/G.M.Wt ) * 6.023*10^23

                              = 80*6.023*10^23/154   = 3.13*10^23 molecules>>>>>>answer

A counter-current packed tower is to be designed to recover 90% carbon tetrachloride (CCl4) from an air-CCl4 mixture containing 5 mol% CCl4. The gas rate will be 800 kg/h m2 of tower cross section. A non-volatile CCl4-free organic oil of molecular weight 260 is to be used as solvent. The solvent rate should be twice the minimum. The tower will be operated at 30°C and 1 atm pressure. Under the operating condition, the equilibrium relation is given by y=20x, where...
