Solution

The correct option is A (i), (ii), and (iv)
The formula for calculating concentration:

Mass by volume percentage =
$\frac{m a s s o f s o l u t e}{v o l u m e o f s o l u t i o n} \times 100$

Volume by volume percentage =
$\frac{v o l u m e o f s o l u t e}{v o l u m e o f s o l u t i o n} \times 100$

Mass by mass percentage =
$\frac{m a s s o f s o l u t e}{m a s s o f s o l u t i o n} \times 100$

Mass of solution = mass of solute + mass of solvent.
