00:01
So to solve for this, just remember that n .a.
00:06
3 .o .4 or sodium phosphate will dissociate in a solvent such as water.
00:11
And the equation for the dissociation will be.
00:14
That's right here.
00:16
Disodium phosphate.
00:18
A 3 .04, this will dissociate to sodium, sodium ion, and phosphate.
00:25
Okay.
00:26
This is 3 minus.
00:27
And so to balance our equation we'll write here three so now we have a balance equation and if we have the larity which is 0 .350 moles of sodium phosphate this is moles per liter the formula for that is most of salutes our solute here is sodium phosphate okay oh sorry this is you salute over the volume of the solution in liters.
01:00
Okay, this is the volume of the solution in liters.
01:03
And if we assume that we have, assume, let's assume that we have one liter of solution.
01:11
Okay.
01:12
So that means the mole of the solute.
01:15
So that means mole solute or moles of n .a.
01:20
T .p...
