Answer:
<h3>The answer is 3.97 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of metal = 33.7 g
volume = 8.49 mL
So we have
We have the final answer as
<h3>3.97 g/mL</h3>
Hope this helps you

Explanation:
Principle Quantum Numbers : It describes the size of the orbital and the energy level. It is represented by n. Where, n = 1,2,3,4....
Azimuthal Quantum Number : It describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1).For l = 0,1,2,3... the orbitals are s, p, d, f...
Magnetic Quantum Number : It describes the orientation of the orbitals. It is represented as . The value of this quantum number ranges from -l to +l.
Spin Quantum number : It describes the direction of electron spin. This is represented as s.
