Computation of molarity of a solution using moles and millimoles

A solution is prepared by dissolving 1.26 g AgNO3 in a 250- ml volumetric flask and diluting to volume. Calculate the molarity of the silver nitrate solution. How many millimoles of AgNO3 were dissolved?

Solution Preview

moles = (moles/liter) x liters
= molarity x liters
The liter is an impractical unit for the relatively small ...
