The volume of the substance is 61.4 litres.
Explanation:
Specific density is the ratio of density of a substance at a given temperature with the density of reference substance.
Data given:
mass = 750 grams
specific gravity = 12.2
volume=?
The formula to be used:
Specific gravity = 
suppose the other substance is water so its density is 1g/ml at 4 degrees
Putting the values to the equation:
density of the object = 1 x12.2
density of the substance = 12.2
Now using the formula:
density = 
putting the values in the equation:
volume = 
= 61.4ml is the volume of the substance.

See explanation
Explanation:
The p orbital is threefold degenerate. This implies that the p-sublevel is composed of three orbitals; px, py and pz.
According to Hund's rule, electrons occur singly when filling degenerate orbitals before pairing takes place. Since the three orbitals are degenerate, any of px, py or pz may be first filled.
If one lobe of any of the px, py or pz is first filled, the next electron must go into the next degenerate orbital. When all are filled, pairing of electron spins may now begin.

Answer:
6.37.
Explanation:
What is given?
[H (+)] = 4.25 x 10⁻⁷ mol/dm³
Step-by-step solution:
First, let's see the formula to calculate the pH based on the hydrogen ion concentration (H (+)):
![pH=-log\lbrack H^+].](https://tex.z-dn.net/?f=pH%3D-log%5Clbrack%20H%5E%2B%5D.)
*Logarithm must be in base 10!
Our given concentration of hydrogen ion is 4.25 x 10⁻⁷ mol/dm³. Remember that the units of concentration must be in M (mol/L) but in this case, 1 dm³ equals 1 L, so based on this, we have that:
So, we can replace this value in the formula of pH:
![pH=-log\lbrack4.25\cdot10^{-7}]\approx6.37.](https://tex.z-dn.net/?f=pH%3D-log%5Clbrack4.25%5Ccdot10%5E%7B-7%7D%5D%5Capprox6.37.)
The pH of milk would be 6.37 which means that is slightly acid (weak acid).
