Question

What is the concentration of a solution, expressed in g/100 mL, if 25 g of solute dissolved in 40 mL of water?

Answer 1

`"Solubility"-=62.5*g*100*mL^-1`.............

Explanation:

We want `"Concentration"="Mass of solute"/"100 mL volume of solvent"`.

We make the reasonable assumption that the volume of solution is equal to `40*mL`.

And so we set up the quotient.......

`(25*g)/((40/100)*mL)=62.5*g*(100*mL)^-1`..........
