Chlorine is found as two isotopes, Cl-35 and Cl-37 (or and Cl). The atomic mass of the Cl-35-isotope is 34,96885 amu while the Cl-37-isotope has an atomic mass equal to 36,96590 amu ( The textbook use this unit for atomic mass, we could as well have used the recommended unit «u»). In the Periodic Table given in the textbook the molar mass of Chlorine is given as 35,45 g/mol.

There are two naturally occurring isotopes of chlorine. 35^CI has a mass of 34.9689 amu. 37^CI has a mass of 36.9659 amu. Determine the abundance of each isotope.
The isotope chlorine-35 has a mass of 34.969 amu , and the isotope chlorine-37 has a mass of 36.966 amu . Given that 75.5 % of all chlorine atoms found in nature are chlorine-35 and 24.5 % are chlorine-37, find the atomic mass of chlorine, Cl(atomic number 17).
Question 3 (2.5 points) Chlorine has two naturally occurring isotopes. The isotope C1-35 (mass = 35.0 amu) makes up 75.8% of the sample, and the isotope CH-37 (mass = 37.0 amu) makes up 24.2% of the sample. What is the average atomic mass for chlorine? A) 36.0 amu B) 35 amu C) 36.6 amu D) 35.5 amu E) 35.521 amu
Chlorine has two isotopes. The lighter one has an atomic mass of 34.969 atomic mass units (amu), and the heavier has a mass of 36.966 amu. If the average atomic mass on another planet is 35.625 amu, what percentage is the lighter isotope? Give your answer to the nearest whole percent.
A mysterious newly discovered element is found to consist of two isotopes I and II. It is found that the relative abundance of isotope I is equal to 68.12%. If isotope I has a mass of 308.72 amu and isotope II has a mass of 311.19 amu, then what is this element's average atomic mass?

8. An element has two naturally occurring isotopes. Isotope 1 has a mass of 120.9038 amu and a relative abundance of 57.4%. Isotope 2 has a mass of 122.9042 amu. Find the atomic mass of this element and, by comparison to the periodic table, identify it.
The atomic mass of magnesium on the periodic table is based on three isotopes, ^24_12Mg, ^25_12Mg, and^26_12Mg. If a fourth isotope is discovered, it would change the abundances of all the others, and it would change the molar mass listed on the periodic table. Calculate the molar mass of magnesium, based on the masses and abundances given below.[^23_12Mg mass = 22.9862, abundance 22.50%] [^24_12Mg mass = 23.9850, abundance 62.49%] [^25_12Mg mass = 24.9858, abundance 10.20%]^26_12Mg mass = 25.9826, abundance 4.810%]
