in a mixture of 1.90 mol of gas, 0.85 mol are nitrogen (n2) molecules. what is the mole fraction of n2 in this mixture?
Nostrana [21]

0.447 is the mole fraction of Nitrogen in this mixture.

mole fraction of nitrogen= moles of nitrogen/total moles

mole fraction of nitrogen=0.85/1.90

mole fraction of nitrogen=0.447

The product of the moles of a component and the total moles of the solution yields a mole fraction, which is a unit of concentration measurement. Because it is a ratio, mole fraction is a unitless statement. The sum of the components of the mole fraction of a solution is one. In a mixture of 1 mol benzene, 2 mol carbon tetrachloride, and 7 mol acetone, the mole fraction of the acetone is 0.7. This is computed by dividing the sum of the moles of acetone in the solution by the total number of moles of the solution's constituents:

choose a reasonable mechanism for the formation of cyclohexylbenzene from the reaction of benzene, cyclohexene, and sulfuric aci
vagabundo [1.1K]

The reasonable mechanism for the formation of cyclohexylbenzene from the reaction of benzene, cyclohexene, and sulfuric acid is Friedel craft alkylation.

In the Friedel craft alkylation cyclohexylbenzene from the reaction of benzene, cyclohexene, and sulfuric acid. in the first step the cyclohexene produced carbocation in the presence of sulfuric acid by protonation. in the second step the `the carbocation undergoes nucleophilic by the benzene ring and produced cyclohexylbenzene. this is the mechanism  followed in the formation of the cyclohexylbenzene by the Friedel craft alkylation.

Thus, The reasonable mechanism for the formation of cyclohexylbenzene from the reaction of benzene, cyclohexene, and sulfuric acid is Friedel craft alkylation.
