Answer: The freezing point depression is 
Explanation:
Depression in freezing point is given by:
= Depression in freezing point
= freezing point constant = 
m= molality = 
Thus freezing point depression is
Explanation:
a. Average kinetic energy is directly proportional to absolute Kelvin temperature of a gas.
Yes
b. There are no attractive forces and repulsive forces between gas molecules.
Yes
C. Atoms are neither created nor destroyed by ordinary chemical reactions.
No
d. The volume occupied by all of the gas molecules in a container is negligible compared to the volume of the container
Yes
The kinetic molecular theory is one of such theories used to explain the forces between molecules and the energy they posses.
According to the theory;
- The temperature of gas is proportional to the average kinetic energy.
- Molecules are independent of one another and the force of attraction and repulsion between them is negligible.
- volume occupied by gases is negligible compared to the volume of the container.
Law of conservation of matter states that "atoms are neither created nor destroyed by ordinary chemical reactions".

Hey there!
MgCl₂
Find molar mass of magnesium chloride.
Mg: 1 x 24.305
Cl: 2 x 35.453
--------------------
95.211 grams
One mole of magnesium chloride has a mass of 95.211 grams.
We have 2.40 moles.
2.40 x 95.211 = 228.5
To 3 sig figs this is 229.
The mass of 2.40 moles of magnesium chloride is 229 grams.
Hope this helps!
Answer:
Va = (MbVb)/Ma
Explanation:
Divide both sides by Ma and voila!
By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom.
