Question

the chlorine in a 0.12g sample of 95% pure magnesium chloride is to be precipitated as silver chloride, calculate the volume of 0.100m of silver nitrate solution required to precipitate the chloride and give a 100% excess.

Answer 1

Here is a worked example of a stoichiometry problem. After you have obtained the moles of AgNO3 needed, then moles = M x L and double the volume to obtain the 100% excess.
