Answer:
positively charged nucleons are 24
Explanation:
Given element:
₂₄⁵⁰ Cr
The superscript before the symbol of the atoms is mass number
The subscript before the symbol is the atomic number
Cr is the symbol of the atom
Now,
Atomic number is the number of protons in an atom.
The protons are the positively charged particles in an atom.
For this specie, the positively charged nucleons are 24
Answer:
The answer is
<h2>0.087 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of liquid = 2.6 g
volume = 30 mL
The density is
We have the final answer as
<h3>0.087 g/mL</h3>
