The values missing in the question has been assumed with common sense so that the concept could be applied
Initial volume of the AICI3 solution
Initial Molarity of the solution
Final molarity of the solution
Final volume of the solution
From Law of Dilution,
Final Volume of the solution 
I don’t know if I am right but I think it is symbol for the first one and the second one is formula.
Answer:
F - O - S - Mg - Ba
Explanation:
as you move left to right on the periodic table the number of electrons increase.
Answer:
A. More mass
C. Shorter distance between them
Explanation:
The two characteristics of a body experiencing greater gravitational force are that they have mass and a shorter distance between them.
This is conformity with Newton's law of universal gravitation.
The law states that "every object attracts one another with a force that is directly proportional to their masses and inversely proportional to the square of the distance between them".
This law implies that the more the mass of two bodies, the more the gravitational force of attraction. And that the shorter the square of the distance between them, the more the attraction.
Given :
Volume , V = 500 mL .
Molarity , M = 0.5 M .
Molecular mass of NaCl is
