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?

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b. b. at twice the distance, the magnitude of the field is 2b. c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
