Answer:
The answer to your question is 19.5 moles
Explanation:
Data
moles = ?
Volume = 6.5 l
Molarity = 3 M
Molarity is a unit of concentration that relates the number of moles by the volume (liters).
Formula
Molarity = moles / Volume
-Solve for moles
moles = Molarity x Volume
-Substitution
moles = 3 x 6.5
-Result
moles = 19.5
n=m/M
8.0g÷58.10g/mol=0.14mol
V=n/c
0.14mol÷0.89M=0.16L=1.6×10²mL
Woah, that doesn't look like high school. That's gotta be college level.
The answer is K3PO4(s) → 3K+(aq) + PO43–(aq) since water-soluble ionic tripotassium phosphate dissociates completely into K+ and PO43– ions when dissolved, that is, no K3PO4 remains in the solution. Carbonic acid H2CO3 and acetic acid CH3COOH are weak electrolytes since they are weak acids that do not completely ionize, while nonelectrolyte CH3OH do not dissociate into ions.
