Question

A solution contains 75gm of common salt in 425gm of water calculate the mars percentage of solution

Answer 1

Answer :

• Mass percentage of the solution = 15%.

Step-by-step explanation :

Given that,

• Mass of solute (common salt) = 75 g.
• Mass of solvent (water) = 425 g.

$\hrulefill$

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

⇒ 75 g + 425 g

⇒ 500 g

We know,

$\rm{Mass\:\%=\dfrac{Mass\:of\:solute}{Mass\:of\:solution}\times{}100}$

Putting the values, we get,

$\implies\rm{Mass\:\%=\dfrac{75\:g}{500\:g}\times{}100}$

$\implies\rm{Mass\:\%=\dfrac{7500}{500}}$

$\implies\rm{Mass\:\%=}\:\bold{15\%.}$

Answer 2

$\huge\sf\pink{Answer}$

☞ Mass percentage of the solution is 15%

━━━━━━━━━━━━━

$\huge\sf\blue{Given}$

✭ Mass of solute = 75 g

✭ Mass of solvent = 425 g

━━━━━━━━━━━━━

$\huge\sf\gray{To \:Find}$

◈ Mass by Mass % of solution?

━━━━━━━━━━━━━

$\huge\sf\purple{Steps}$

So first we got to find the mass of the solution,so for that we shall use, Mass of solution = Mass of solute + Mass of solvent

Substituting the given values,

➝ $\sf 75 \ g + 425 \ g$

➝ $\sf \red{500 \ g}$

So now to find the mass by mass percentage of solution we use,

$\sf \underline{\boxed{\sf \dfrac{Mass \ of \ Solute}{Mass \ of , Solution}\times 100}}$

Substituting the values,

➳ $\sf Mass \% = \dfrac{75}{5\cancel{00}}\times 1\cancel{00}$

➳ $\sf Mass \% = \dfrac{75}{5}$

➳ $\sf \orange{Mass\% = 15\%}$
