Zinc has an average atomic mass of 65.37 amu. Jack is trying to figure out what the most abundant isotope of zinc is, but he doe
Mekhanik [1.2K]

Zinc's most abundant isotope : Zinc-65

<h3>Further explanation </h3>

Isotopes are atoms whose no-atom has the same number of protons while still having a different number of neutrons.

So Isotopes are elements that have the same Atomic Number (Proton)

Atomic mass is the average atomic mass of all its isotopes

In determining the mass of an atom, as a standard is the mass of 1 carbon-12 atom whose mass is 12 amu

Mass atom X = mass isotope 1 . % + mass isotope 2.%

To decide zinc's most abundant isotope, then choose the closest mass number

or we can check the difference with the average mass number, if the value is the smallest, then that isotope has the largest abundant

  • Zinc-64

\tt \dfrac{65.37-64}{65.37}=0.021

  • Zinc-65

\tt \dfrac{65.37-65}{65.37}=0.005

  • Zinc-68

\tt \dfrac{68-65.37}{65.37}=0.04

  • Zinc-66

\tt \dfrac{66-65.37}{65.37}=0.009

The closest = Zinc-65(the smallest)

How do the Earth and Moon compare in terms of gravitational force?
AleksAgata [21]
C. Earth's gravitational force is stronger than the Moon's.

Since Earth has a far larger mass than the Moon, its gravitational force is also higher.
