How many liters of a 5.00 M solution of Na3PO4 are needed to have 4.00 equivalents ?
First we need the equation for dissolving the salt, Na3PO4 → 3 Na+1 + PO4-3
An equivalent is a mole of charges, either + or -, but not both, they are not added
the conversion factor is 1 mol =
Blank 1. Fill in the blank, read surrounding text.
