Question

A 60 gm solute is dissolved in 90 gm of water to make a saturated solution. Calculate the concentration of solution in terms of mass by mass​

Answer 1

Answer :

➥ The Concentration of the Solution = 40%

Given :

➤ Mass of Solute = 60 gm

➤ Mass of Solvent (water) = 90 gm

To Find :

➤ Concentration of the Solution = ?

Solution :

To find the concentration of the solution, first we need it find the mass of solution, then after we find the concentration of the solution.

As we know that

→ Mass of Solution = Mass of Solute + Mass of Solvent

→ Mass of Solution = 60 + 90

→ Mass of Solution = 150 gm

Now, we have mass of solute and mass of solution,

• Mass of Solute = 60 g
• Mass of Solution = 150 g

☃️ So let's find the Concentration of the Solution by using the formula:

$\tt{:\implies \footnotesize{Concentration = \dfrac{Mass \: of \: Solute}{Mass \: of \: Solution} \times 100}}$

$\tt{:\implies Concentration = \dfrac{6 \cancel{0}}{15 \cancel{0}} \times 100}$

$\tt{:\implies Concentration = \dfrac{ \cancel{ \: 6 \: }}{ \cancel{15}} \times 100}$

$\tt{:\implies Concentration = 0.4 \times 100}$

$\bf{:\implies \underline{ \: \: \underline{ \red{ \: \: Concentration = 40\% \: \: }} \: \: }}$

║Hence, the Concentration of the Solution is 40%.║
