Question

$\huge{ \underline{ \underline{ \sf {question}}}}$

A solution contains 30g of sugar dissolved in 370g of water. Calculate the concentration of this solution.
​

Answer 1

Answer:

We know that concentration of solution=

Mass of Solute/Massof solution x 100 Here,

Mass of solute (sugar) = 30 g

Mass of Solvent (water) = 370 g

So, Mass of solution = Mass of solute + Mass of solvent

= 30 + 370

= 400

Now,

Putting the values of ‘mass of solute’ and ‘mass of solution’ in the above formula, we get:

Concentration of solution

=30/400 x 100

=30/4

=7.5 %

Hope this helps you.

Answer 2

${\large{\underline{\underline{\pmb{\frak{Let's\;understand\;the\;concept:-}}}}}}$

☀️  As per the given information, we have mass of sugar and water. We need to calculate the concentration of the solution. Firstly, calculate the mass of solution and then Concentration in order to get the required answer.  

${\large{\underline{\underline{\pmb{\frak{Given:-}}}}}}$

Mass of Sugar in the solution is 30g  

Mass of water in the solution is 370g  

${\large{\underline{\underline{\pmb{\frak{To\;find:-}}}}}}$

Concentration of this solution

${\large{\underline{\underline{\pmb{\frak{solution:-}}}}}}$

❍  To calculate the concentration of the solution we must know that ::  

$\sf \bigstar \;\; Concentration\;of\;solution = \dfrac{Mass\;of\;Solute}{Mass\;of\;Solution} \times 100 \%$

Where,  

• Solute is sugar  
• Solution is sugar with water  

⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━

Finding the Mass of Solution :-

Mass of Sugar + Mass of Water  

⤳ 30g + 370g  

⤳ 400g

Finding the Concentration :-

⤳ 30/400 × 100%  

⤳ 3/40 × 100%

⤳ 3/4 × 10%

⤳ 30/4 %

⤳ 7.5%  

⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━

• Henceforth, the concentration of sugar solution is 7.5 %
