19F) and the Cl chlorine possesses two isotopes (i.e. 35Cl and 37Cl). Some isotopes are unstable forms of elements; they are radioactive and are called radioisotopes: for example, 14C is a radioisotope of carbon. For any element, there is one isotope that is the most abundant in ...
3. Compute Mass of Each Element Multiply the number of atoms by the atomic weight of each element found in steps 1 and 2 to get the mass of each element in (35Cl2): Molar Mass (g/mol) Cl (Chlorine) 70 × 35.453 = 2481.71 4. Sum Each Element's Mass Finally, add together the to...
Average atomic mass, given in atomic mass units (amu), is always similar to mass number, but it is not a whole number. Average Atomic Mass: Example Chlorine-35 has an atomic mass of 34.969 amu and accounts for 75.77% of chlorine on Earth. ...

What is its mass number? A neutral atom has an atomic number of 12 and an atomic mass of 25. How many neutrons are in it? Thoroughly describe what atomic mass is. What are the atomic number (Z), mass number (A), and symbol of the chlorine isotope with 18 neutrons? An isotope ...
Figure 3. Table salt, NaCl, contains an array of sodium and chloride ions combined in a 1:1 ratio. Its formula mass is 58.44 amu. Note that the average masses of neutral sodium and chlorine atoms were used in this computation, rather than the masses for sodium cations and chlorine anions...
1. Count The Number of Each Atom The first step to finding the molar mass is to count the number of each atom present in a single molecule using the chemical formula, C10Cl35: ElementNumber of Atoms C (Carbon) 10 Cl (Chlorine) 35 2. Find Atomic Mass of Each Element Next, using the...
