1386g

Explanation:

Solubility of a solute is the ability of the solute to mix into a liquid (the solvent). It measures the highest amount of substance mixed into a liquid solvent while they are both at equal amounts.

if 14g dissolved in 100cm3

the amount that will dissolve in 1000cm3 = 14 x 1000 / 100

=1400g

To form a saturated solution, 1400 - 14 = 1386g must be added.
