Na3po4 dissolves in water to produce an electrolytic solution. what is the osmolarity of a 2. 0 × 10-3 m na3po4 solution?
vichka [17]

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,

Na_{3}PO_{4} ⇒ 3Na^{+} + PO_{4} ^{-}

3  Moles of Na_{} ^{+} + 1 mole PO_{4} ^{-} = 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 Na_{3} PO_{4} .dissolved =4

Since we know that,

Na_{3} PO_{4} = 2.0 * 10^{-3} M

Osmolarity =

4*2.0*10^{-3} M = 8.0 * 10^{-3}  osmol L -10s

Thus, the Osmolarity of given solution is 0.008 osmol/L.

Two chemicals A and B are combined to form a chemical C. The rate, or velocity, of the reaction is proportional to the product o
Marizza181 [45]

Answer:

30.6 g of C is formed.

Explanation:

2A + B → C

Average rate of reaction = 2[A]/Δt = [B]/Δt = [C]/Δt

Average rate of reaction = [C]/Δt

Average rate of reaction  = 15 g / 9 min

Average rate of reaction  = 1.7 g of C / min

Average rate of reaction = [C]/Δt

[C] = Average rate of reaction x Δt

[C] = 1.7 g of C / min x 18 min

[C] = 30.6 g of C
