Answer:
8.533 Mev/nucleon
Explanation:
The given elements is:-
Atomic number : It is defined as the number of electrons or number of protons present in a neutral atom.
Thus, the number of protons = 25
Mass number is the number of the entities present in the nucleus which is the equal to the sum of the number of protons and electrons.
Mass number = Number of protons + Number of neutrons
55 = 25 + Number of neutrons
Number of neutrons = 30
Mass of neutron = 1.008665 amu
Mass of proton = 1.007825 amu
Calculated mass = Number of protons*Mass of proton + Number of neutrons*Mass of neutron
Thus,
Calculated mass = (25*1.007277 + 30*1.008665) amu = 55.441875 amu
Actual mass = 54.9380451 amu
Mass defect = Δm = |54.9380451 - 55.441875| amu = 0.5038299 amu
The conversion of amu to MeV is shown below as:-
1 amu = 931.5 MeV
So, Energy = 0.5038299*931.5 MeV= 469.317552 MeV
Total number of nucleons in the atoms = 55
<u>So, Energy = 469.317552/55 MeV/nucleon = 8.533 Mev/nucleon</u>

<h3><em>Further Explanation</em></h3>Density is a quantity derived from the mass and volume
density is the ratio of mass per unit volume
With the same mass, the volume of objects that have a high density will be smaller than type
The unit of density can be expressed in g / cm3 or kg / m3
Density formula:
ρ = density
m = mass
v = volume
A common example is the water density of 1 gr / cm3
The mass itself is often equated with weight, even though it is different. Mass is the amount of matter in the matter while weight is related to the gravitational force
<em>Known variable</em>
volume gold bar 7.379 × 10⁻⁴ m³
a density of 19.3 g/cm³
<em>Asked</em>
the mass of a gold bar
<em>Answer</em>
volume is known to be 7.379 × 10⁻⁴ m³, then we change it first to units of cm³ adjusting to units of density
7.379 × 10⁻⁴ m³ = 7.379 × 10² cm³
then:
mass = volume x density
mass = 7.379 × 10² cm³ x 19.3 g/cm³
mass = 1.424 x 10⁴ gram
