The directions state "weigh about 5 grams of sodium chloride". Give minimum and maximum amounts of sodium chloride that would satisfy these instructions.

Answer 1

You don't provide enough data to give an accurate answer but usually these problems would indicate about 4-6 grams.
If this is a titration problem you want enough to use about 35-45 mL of the titrant. If a grqavimetric procedure it depnds upon what kind of balance you used. Does it weigh to the nearest 0.1 mg or to the nearest 0.0001 mg.
