Question

12g of sodium chloride is dissolved in 75g of water at 65°C. Find the solubility os sodium chloride in g/100g of water at 65°C

Answer 1

Answer:

Explanation:

Mass of solute i.e, for the sodium chloride =58.5g

Mass of solvent i.e, for the water=100g

Mass of solution=58.5+100=158.5g

The concentration of solution in terms of mass percentage is given as,

 

                          =  

Massofsolution×100

Massofsolute

​

 

                           =  

158.5×100

58.5
