Given :

Molarity of Na_3PO_4 , M = 0.213 M .

To Find :

How many ml of 0.213 M of Na_3PO_4 are required to deliver 66.4 mmol Na^+.

Solution :

Volume required  :

V=[\text{ 66.4 mmol of }Na^+] + [\dfrac{\text{1 mm of }Na_3PO_4}{\text{3 mmol of }Na^+}]+[\dfrac{\text{1 ml }Na_3PO_4}{\text{0.213 mmol of }Na_3PO_4}]

So ,

V=\dfrac{66.4}{3\times 0.213}\ ml\\\\V=103.91\ ml

Therefore , volume of Na_3PO_4 required is 103.91 ml .

Hence , this is the required solution .

What does Gibbs free energy predict?
kicyunya [14]

Answer:

It predicts whether or not a reaction will be spontaneous.

Explanation:

The equation;

∆G= ∆H - T∆S enables us to obtain the Gibbs free energy of a chemical process.

The Gibbs free energy value tells us whether a chemical process will be spontaneous or not.

When;

∆G>0 the reaction is not spontaneous

∆G=0 the reaction is at equilibrium

∆G<0 the reaction is spontaneous
