i’m guessing that is the answer as the question is unreasonable
- No of protons=No of electrons=15
<h3>Mass no:-No of neutrons+No of protons </h3>

Now
- It has atomic no 15 hence its Phosphorus(P)
Electronic configuration:-
.

Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.
The final volume reading on the graduated cylinder is 12.52ml
Density = mass / volume
Volume = mass / density
Volume of zinc = 2.83/7.14
Volume of zinc = 0.3963
Initial volume = 12.13 ml
Total volume = initial volume+ volume of zinc
Total volume = 12.13 + 0.3963
Total volume = 12.5263 = 12.52 ml
