Answer:
82.1
Explanation:
Isotopes of the same element are atoms of the same element (so, having same number of protons) having a different number of neutrons (and so, a different atomic mass).
In this problem, this element has 3 different isotopes, with atomic mass (in atomic mass units, a.m.u.) and relative abundance listed below:
1) 78.9 12.6%
2) 80.9 13.9%
3) 82.9 73.5%
In order to calculate the relative atomic mass unit of this element, we have to calculate the weighed average of the relative atomic mass of each isotope.
This means that we can calculate it as the sum of each atomic mass unit multiplied by the relative frequency:
where is the atomic mass of each isotope and
the relative frequency. Therefore, we find:
Answer:The weight of Object F will be times the weight of Object E if both objects are placed on the same planet.
Explanation:
Mass of the object E,= 4800 kg
Mass of the object F,== 600 kg
Since they are on the same planet same gravitation force will be exerted on them by the gravity of the planet.
The weight of Object F will be times the weight of Object E if both objects are placed on the same planet.
