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.

The control room is similar to the nucleus, because the nucleus is in charge of cell functions.
Answer:
Ethane molecules have no hydrogen bonds and need less energy to separate.
Explanation:
Ethane: has no hydrogen bonding, it has low melting, boiling points, and is a gas at room temperature.
Water: has strong hydrogen bonding between H and O, has relatively high melting and boiling points.
