Answer:
The answer is 1. A type of acid that completely reacts with water.
Explanation:
A strong acid dissociates completely in water to release hydrogen ions as the only positive ions.
This is the simple definition of Arrhenius acid.
NaCl molar mass 58.4 g/mol
moles of NaCl = .35 g * 1 mol/58.4 g = 0.005993 mol
volume of solution = 150 mL = 0.15 L
molarity = mol/vol(in L)
[NaCl] = 0.005933mol/0.15L = 0.03995 M = 0.040 M
