Question
The mass (g) of a single 35Cl<sub>2</sub> is closest to:
(Use the isotopic mass of 35Cl = 34.968 amu.)
Group of answer choices
Solution
To find the mass of a single 35Cl2 molecule, you need to add the mass of two 35Cl atoms because Cl2 is a molecule made up of two chlorine atoms.
-
The given isotopic mass of 35Cl is 34.968 amu.
-
Since a Cl2 molecule is made up of two 35Cl atoms, you need to multiply this mass by 2.
34.968 amu * 2 = 69.936 amu
So, the mass of a single 35Cl2 molecule is closest to 69.936 amu.
