Question

30g of sugar is dissolved in water to form 200 gram of sugar solution calculate the concentration in terms of mass by mass percent

Answer 1

Answer:

Concentration of sugar = 15%

Concentration of solvent = 85%

Explanation:

Given :

• Mass of the solute = Mass of sugar = 30 grams

• Mass of the solution = Mass of sugar solution = 200 grams

To find :

• Concentration of sugar using mass by mass per cent

Concentration of solute = Mass of solute / Mass of solution × 100

Concentration of sugar = 30/200 ×100

Concentration of sugar = 30/2

Concentration of sugar = 15%

Concentration of solute = 100%-concentration of sugar

Concentration of solute = 100%-15%

Concentration of solute = 85%

The concentration of sugar is 15% and concentration of solute is 85%

Answer 2

$\large\underline\bold{Answer:-}$

$\large\underline\bold{Given:-}$

$\sf\ Mass \:of\:sugar= 30g$

$\sf\ Mass\:of\:sugar\: Solution=200g$

$\large\underline\bold{To\: Calculate:-}$

$\sf\ Concentration\:of\:sugar\:mass\:by\:mass\: percent$

$\large\underline\bold{Required\: Solution:-}$

$\sf\ Concentration\:of\:Sugar:-$ $\sf\large\ \frac{Mass\:of\:solute}{Mass\:of\: Solution}×100$

$\sf\ =\frac{30}{200}×100$

$\sf\ =30×2$

$\large\underline\bold\purple{=15\%}$

$\sf\ Concentration\:of\:solute(mass\:percent)=$

$\sf\ 100\%-concentration\:of\:sugar$

$\sf\ =100\%-15\%$

$\large\underline\bold\purple{=85\%}$

$\sf\ Hence\: Concentration\:of\:Sugar=15\%$

$\sf\ Concentration\:of\:Solute=85\%$

$\large\underline\bold{Related\: information:-}$

$\sf\ Concentration\:of\: Solution=\frac{Amount \: of\:solute}{Amount\:of\: solution}$

Or

$\sf\ Concentration\:of\: Solution=\frac{Amount \: of\:solute}{Amount\:of\: solvent}$

$\sf\ Mass \:by\:mass\: percentage\:of\: solution:- \frac{Mass\:of\:solute}{Mass\:of\: solution}×100$

$\sf\ Mass\:of\: solution=Mass\:of\:solute+Mass\:of\: solvet$

$\sf\ Mass\:by\: volume\: percentage\:of\: solution=\frac{Mass\:of\: volume}{Volume\:of\:Solution}×100$

$\sf\ Volume\:of\: Solution=Volume\:of\:solute+volume\:of\:solvent$
