Now try the following question.
F7. MASS OF SOLUTE FROM CONCENTRATION & VOLUME, m = c V M - 2
Now attempt the following related problems.
While Q7. is similar, part (b) does include an hydrated compound and its 'water of crystallization' must be considered when calculating the molar mass. These H-O-H molecules form an integral part of the solid structure; this is true generally for crystalline hydrates.
