A Solution contains 30g of of sugar dissolved in 370 g of water. calculate the concentration of this Solution​

Answer 1

$\Large{\boxed{\underline{\overline{\mathfrak{\star \: Question :- \: \star}}}}}$

❥ A Solution contains 30g of of sugar dissolved in 370 g of water. calculate the concentration of this Solution.

$\Large{\underline{\underline{\bf{AnSweR:-}}}}$

$\large{\boxed{\bold{The\: Concentration\:of\:this\:sugar\: Solution\:=\:7.5\: percent}}}$

$\Large{\underline{\underline{\bf{GiVen:-}}}}$

✒ Mass of solute ( sugar ) ↠ 30 g

✒ Mass of solvent ( water ) ↠ 370 g

Now ,

$\Large{\underline{\underline{\bf{To find :-}}}}$

✒ Calculate the concentration of this sugar Solution

$\large{\boxed{\bold{Formula\: required}}}$

$\large{\boxed{\bold{Concentration\:of\: Solution\:=\:Mass\:of\:solute\:÷\:Mass\:of\: Solution\:×\:100}}}$

✒ Mass of Solution ↠Mass of solute + Mass of solvent

$\Large{\underline{\underline{\bf{SoLuTion:-}}}}$

✦ Here ,

✒ Mass of solute ( sugar ) ↠ 30 g

✒ Mass of solvent ( water ) ↠ 370 g

❥ So ,

✒ Mass of Solution ↠Mass of solute + Mass of solvent

✒ Mass of Solution ↠30 + 370

✒ Mass of Solution ↠400 g

$\large{\boxed{\bold{Concentration\:of\: Solution\:=\:Mass\:of\:solute\:÷\:Mass\:of\: Solution\:×\:100}}}$

Now,

✒ putting the values of 'mass of solute' and 'mass of solution' in the above formula , we get :

✒ Concentration of Solution ↠ 30/ 400 × 100

✒ Concentration of Solution ↠ 30/4

✒ Concentration of Solution ↠ 7.5 %

∴ The concentration of this sugar solution is 7.5 %

☞ Extra shots :-

❃ Concentration of a solution:

✒ Concentration of solution depend on number moles of solute particles in solution.

✒ Mass percentage of solute (Weight/Weight). Mass of the solute present in 100 parts by mass of solution mass % of solute = Wb / Wa + Wb x 100

✒ Volume percentage of solute (v/v). Volume of solute present in 100 parts by volume of solute. Volume % of solute = Vb / Va + Vb x 100

✒ Mass / Volume percentage of solute = Wb / V solution x 100. Mass of solute present in 100 parts by volume of solution.
