Asample of chlorine has two naturally occurring isotopes. the isotope cl-35 (mass 35.0 amu) makes up 75.8% of the sample, and the isotope cl-37 (mass = 37.0 amu) makes up 24.3% of the sample. what is the average atomic mass for chlorine?

Explanation:

As in any sample you will have 75.8% of Cl-35 iosotopes and 24.3% of Cl-37 iosotopes you can get the average atomic mass as:

gravity

explanation:

iron would move it is magnetic there is a mag field around the current in the wire
