Answer :
The predicted atomic mass of the mixture of two chlorine isotopes, with 40% Chlorine-37 and 60% Chlorine-35, is 36.0 amu.
To calculate the atomic mass of the mixture, we need to consider the relative abundance and atomic mass of each isotope.
Chlorine-37 has an atomic mass of 37 amu and a relative abundance of 40%. Chlorine-35 has an atomic mass of 35 amu and a relative abundance of 60%.
To calculate the atomic mass of the mixture, we multiply the atomic mass of each isotope by its relative abundance and sum the results:
(37 amu * 0.40) + (35 amu * 0.60) = 14.8 amu + 21 amu = 35.8 amu + 21 amu = 56.8 amu
Therefore, the predicted atomic mass of the mixture is 56.8 amu.
The predicted atomic mass of the mixture of two chlorine isotopes, with 40% Chlorine-37 and 60% Chlorine-35, is 36.0 amu. This calculation takes into account the relative abundance and atomic mass of each isotope in the mixture.
