When Na3po4 dissolves in water to produce an electrolytic solution. The osmolarity of a 2. 0 × 10-3 m Na3po4 solution is 0.008osmol/L.
Osmolarity is defined as the number of osmoles of solute particles per unit volume of the solution.
In other words osmolarity is the multiple if molarity
Osmolarity = i× molarity
Here i represents the van't Hoff factor,
⇒ 
3 Moles of 
+ 1 mole 
= 4
The number of moles of particles of solute produced in solution are actually called osmoles.
As a result, the van't Hoff factor will be equal to
i=4 Moles ions produced (osmoles) 1mole 
.dissolved =4
Since we know that,
= 
Osmolarity =
= 
Thus, the Osmolarity of given solution is 0.008 osmol/L.

C) A chlorine atom can form ionic bonds by accepting an electron and covalent bonds by sharing electrons
Explanation:
The statement that best explains the behavior of chlorine is that its atom can form ionic bonds by accepting an electron and covalent bonds by sharing electrons.
- To form an ionic bond, two atoms combines together via electrostatic attraction between them.
- Ionic bonds are formed between metals and non-metals.
- The large electronegativity difference between the two specie is the driving factor.
- In forming NaCl compound, Na donates electron which is accepted by Chlorine.
- This leaves a positive charge on Na and a negative charge on chlorine and the ensuing electrostatic attraction forms an ionic bond.
To form the covalent bond, the chlorine shares their valence electrons between themselves. They have an equal affinity for these electrons and this leads to the formation of a non-polar covalent bond

Answer:
Explanation:
NaNO₃ = Na⁺ + NO₃⁻¹
.497 M .497 M
moles of NO₃⁻¹ = .897 x .497 = .4458 moles
Ca( NO₃)₂ = Ca + 2 NO₃⁻¹
.341 M 2 x .341 M = .682 M
moles of NO₃⁻¹ = .813 x .682 = .5544 moles
Total moles = .4458 moles + .5544 moles
= 1.0002 moles
volume of solution = 897 + 813 = 1710 mL
= 1.710 L
concentration of nitrate ion = 1.0002 / 1.710 M
= .585 M
Balanced equation: 10 CaCo3 + 20 HCl = 10 CaCl2 + H20 + 15 Co2
