Answer:
1. Molality.
2. Concentration.
3. Percent by mass.
4. Mole fraction.
Explanation:
Molarity is the measurement by which the number of moles is measured by a solute. The solution here is one liter respectively.
Concentration is the product which is emerged when the amount of the solute is divided by the amount o the solvent or solution.
Mole fraction refers to the number of component moles divided by the number of the solution moles.

Answer:
#2.
Explanation:
Look at the charges. Both are positive, therefore both are cations.
Answer:
TiCl2
Explanation:
Mass of the chloride of titanium= 1.31 g
Mass of titanium= 0.528 g
Therefore mass of chlorine = 1.31-0.528 = 0.782 g
To determine the empirical formulae of the titanium chloride, divide the mass of each element by its relative atomic mass and divide through by the lowest ratio.
Ti- 0.528/48 = 0.011, Cl- 0.782/35.5 = 0.022
Ti- 0.011/0.011 , Cl- 0.022/0.011
Ti- 1, Cl-2
Hence the required empirical formula is TiCl2
In a water molecule, the oxygen atom and hydrogen atoms share electrons in covalent bonds, but the sharing is not equal. In the covalent bond between oxygen and hydrogen, the oxygen atom attracts electrons a bit more strongly than the hydrogen atoms.
