Question

16 g of a solute is dissolved in 100 ml of water to form saturated solution at 25 degree Celsius. The strength of the solution (in g/L) will be equal to ?

Answer 1

Answer

Given mass of Na OH=16 grams → Solute.

Given mass of water = 100 grams → Solvent

Solubility (in g/100g) =  

solvent

Mass

×100

=  

100

16

​  

×100=16

Solubility of the solution is 16(g/100g)

Weight Percentage =
