Question

A solution contains 40 gm of common salt in 360 gram
of water. calculate the concentration interms of mass
by mass percentage of the solution.​

Answer 1

Answer:

as  of common salt (solute)=40 g

Mass of water (soluted) =320 g

mass of solution=320+40

              =360 g

concentration of solution=

×100=11.11%

Hence, the concentration of the solution is 11.11%

Explanation:

Answer 2

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.
