A liquid that occupies a volume of 9.0 L has a mass of 7.2 kg. What is the density of the liquid in kg/L
1 answer:
Answer:
<h2>Density = 0.8 kg/L</h2>Explanation:
The density of a substance can be found by using the formula
<h3>From the question
mass = 7.2 kg
volume = 9.0 L
Substitute the values into the above formula and solve for the density
That's
<h3>We have the final answer as
<h3>Density = 0.8 kg/L</h3>Hope this helps you

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.
