Ответ:
The mole fraction of benzene will be 0.34 and mole fraction of toluene is 0.66
Explanation:
According to Raoult's law, the vapor pressure of a component at a given temperature is equal to the mole fraction of that component multiplied by the vapor pressure of that component in the pure state.
where, x = mole fraction in solution
According to Dalton's law, the total pressure is the sum of individual pressures.
Thus (1-x0 = (1-0.34)=0.66
Thus the mole fraction of benzene will be 0.34 and that of toluene is 0.66
Ответ:
This is called codon degeneracy. It is also said that the genetic code is redundant, meaning that multiple codons can code for the same amino acid, like for example CCC and CCA both coding Proline.
