Question

2. Who did the old lady mistake Ju fos? Why?​

Answer 1

Given :

Mass of Salt (Solute) = 40g

Mass of Water (Solvent) = 360g

To Find :

Concentration of the Solution

Solution :

$\longmapsto\tt{Mass\:of\:Salt=40g}$

$\longmapsto\tt{Mass\:of\:Water=360g}$

Mass of Solution = Mass of Solute + Mass of Solvent.

$\longmapsto\tt{40+360}$

$\longmapsto\tt\bf{400g}$

Now ,

$\longmapsto\tt\bf{Concentration=\frac{Mass\:of\:Solute}{Mass\:of\:Solution}\times{100}}$

$\longmapsto\tt{\dfrac{{\cancel{40}}}{{\cancel{4}}{\cancel{00}}}\times{1{\cancel{00}}}}$

$\longmapsto\tt\bf{10\%}$

So , The Concentration of the Solution is 10%...

_______________________

Solute :

In a solution , the components which are present in smaller proportion is called as Solute.

Solvent :

In a solution , the components which are present in larger proportion is called as Solvent.

Concentration of Solution :

The relative amount of solute and solvent present in a solution is known as Concentration of Solution.
