b. The solubility of a salt at 0'e is 12. How much salt will 50g of its saturated solution contain at that temperature?
Answers
Answer:
The solubility of salt at 30 ^o C is 50 . Calculate the weight of water required to prepare a saturated solution containing 90 g of salt.
180 GRAM
Step-by-step explanation:
weight of salt = 90 gram,
weight of salt = 90 gram, solubility = 50
weight of salt = 90 gram, solubility = 50sing formula
weight of salt = 90 gram, solubility = 50sing formula solubility of solute =weightofsolventinsaturatedsolutionweightofsoluteinsaturatedsolution×100
weight of salt = 90 gram, solubility = 50sing formula solubility of solute =weightofsolventinsaturatedsolutionweightofsoluteinsaturatedsolution×100or 50=weightofsolventinsaturatedsolutio90gm×100
weight of salt = 90 gram, solubility = 50sing formula solubility of solute =weightofsolventinsaturatedsolutionweightofsoluteinsaturatedsolution×100or 50=weightofsolventinsaturatedsolutio90gm×100so weight of solvent in saturated solution = 5090gm×100=180gm
weight of salt = 90 gram, solubility = 50sing formula solubility of solute =weightofsolventinsaturatedsolutionweightofsoluteinsaturatedsolution×100or 50=weightofsolventinsaturatedsolutio90gm×100so weight of solvent in saturated solution = 5090gm×100=180gmHence 180 gm of water is required to prepare a saturated solution.
