Chlorine CL relative atomic mass is 35.5 this half number is due to
Correct answer: A. Isotopes
- A. Isotopes
- B. A half proton
- C. A half neutron
- D. A half electron
Explanation
The Half number in relative atomic mass of Chlorine (i.e 35.5) is due to two naturally occurring isotopes (Chlorine-35 and Chlorine-37).Chlorine-35 is more abundant isotope(accounting for 75.77% of naturally occurring Chlorine) and it's Atomic Mass is 34.97 amu.Chlorine-37 is less abundant isotope(accounting for remaining 24.33% of naturally occurring Chlorine) and it's Atomic Mass is 36.97 amu.Average atomic mass=(Abundance of Chlorine-35 x Atomic mass of Chlorine-35) + (Abundance of Chlorine-37 x Atomic Mass of Chlorine-37)(0.7577 x 34.97 amu) + (0.2423 x 36.97 amu)=26.52 amu + 8.96=35.48 amu (Rounded of as 35.5 amu)

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
