Jack has a rock the rock has a mass of 14 G and the volume of 12 cm power of 2 that what is the Density of the rock?
1 answer:
Given parameters:
Mass of rock = 14g
Volume of rock = 12cm³
Unknown:
Density of the rock = ?
Density of a substance is the amount of substance it contains per unit volume. Mathematically, this can be expressed as;
Density =
Now simply input the parameters and solve;
Density = = 1.17g/cm³
Density of the rock that Jack has is 1.17g/cm³

Answer:
The valid quantum numbers are l=0, l=-2 and l= 2.
Explanation:
Given that,
n = 3 electron shell
Suppose, the valid quantum numbers are
l = 3
m = 3
l = 0
m = –2
l = –1
m = 2
We know that,
The value of n = 3
Principle quantum number :
Then the principal quantum number is 3. Which is shows the M shell.
So, n = 3
Azimuthal quantum number :
The azimuthal quantum number is l.
Magnetic quantum number :
The magnetic quantum number is
Hence, The valid quantum numbers are l=0, l=-2 and l= 2.
