49 neutrons in each nucleus.
<h3>Explanation</h3>
For each nucleus:
Mass number = Number of protons + Number of neutrons.
The atomic number of a nucleus is the same as its number of protons. The atomic number of the nucleus here is 31. There are 31 protons in each nucleus.
- Mass number = 80;
- Number of protons = Atomic number = 31;
- The number of neutrons is to be found.
Again,
Mass number = Number of protons + Number of neutrons.
80 = 31 + Number of neutrons.
Number of neutrons = 80 - 31 = 49.
The answer is .00834 cg hopefully this helped

Answer:
<h3>The answer is 235.29 mL</h3>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula

From the question.
density = 0.017 g/mL
mass = 4 g
We have

We have the final answer as
