21.5 g of sodium chloride dissolves in 60 g of water at 25^(@) C calculate the solubility of sodium chloride in water at that temperature .
9.72 g fo potassium chlroride dissovles in 30g of water at 70^(@) C calculate the solubility of potassium chloride at that temperature .
Sodium oxide dissolves in water.
When potassium chloride is dissolved in water
7.45g of potassium chloride is dissolved in 100g of water. What will be the molality of the solution ?
5 g of sodium chloride are dissolved 100 g of water to form a solution. Is this solution saturated in nature ?
4 g of a solute are dissolved in 40 g of water to form a saturated solution at 25^(@)C . Calculate the solubility of the solute.
Calculate the total number of ions in 0.585g of sodium chloride.
1.7 g of silver nitrate dissolved in 100 g of water is taken. 0.585 g of sodium chloride dissolved in 100 g of water is added to it an chemical reaction occurs. 1.435 g of silver chloride and 0.85 g of sodium nitrate are formed. Justify that the data obey law of conservation of mass.
When sodium chloride is dissolved in water the solution obtained is
