Question

a solution contains 5.6ml of alcohol mixed with 75ml of water calculate the concentration of this solution.​

Answer 1

GIVEN:-

• $\rm{ Mass\:of\:Solute = 5.6ml(Alcohol)}$

• $\rm{Mass\:of\:Solvent = 75ml(water)}$

TO FIND:-

• Calculate the Concentration of this Solution.

FORMULAE USED:-

• ${\boxed{\rm{\blue{Concentration = \dfrac{Mass\:of\:Solute\times{100}}{Mass\:of\:Solution}}}}}$

Where,

Mass of Solution = Solute + Solvent.

Now,

$\rm{Concentration=\dfrac{Mass\:of\:Solute\times{100}}{Mass\:of\:Solution}}$

$\rm{ Concentration = \dfrac{5.6\times{100}}{5.6 + 75}}$

$\rm{Concentration = \dfrac{\cancel{560}}{\cancel{80.6}}}$

$\rm{Concentration = 6.9\:percent}$.

Hence, The Concentration of the Solution is 6.9%.

• Saturated Solution - The Solution in which no more Solute can be dissolved at a given temperature is known as Saturated Solution.

• Unsaturated Solution- The Solution which contains less Solute than the maximum amount of solute that is capable of being dissolved.

Answer 2

⚜ Given :-

• Alcohol = 5.6ml (Solute.)
• Water = 75ml (Solvent.)

⚜ To Find :-

• Concentration Of Solution.

⚜ Solution :-

Formula Used :-

$\sf\red{Concentration \: = \dfrac{Mass \: of \: solute \: \times 100}{Mass \: of \: solution} }$

We can write Solution As :-

Solution = Solute + Solvent.

$\sf\purple{Concentration \: = \dfrac{Mass \: of \: solute \: \times 100}{Solute+Solvent} }$

Put the values given.

$\sf\pink{Concentration \: = \dfrac{5.6 \times 100}{5.6 + 7.5}}$

$\sf\green{Concentration \: = \dfrac{\cancel{560}}{\cancel{80.6}} = 6.9\% }$

So, The Concentration = 6.9%.
