Question

If 50gr of common salt is dissolved in 200gr of its solutin, the mass percentage of the solution is _____________​

Answer 1

If 50gr of common salt is dissolved in 200gr of its solutin, the mass percentage of the solution is 33.33%

Answer 2

$\LARGE{ \underline{\underline{ \purple{ \sf{Required \: answer:}}}}}$

GiveN:

• Mass of common salt = 50 g
• Mass of the solution = 200 g

To FinD:

• Mass percentage of the Solution?

Step-wise-Step Explanation:

Generally we are required to find the mass percentage in order to determine the concentration of the solution in terms of mass, volume or mass & volume.

Mass percentage can be calculated by:

$\cdot{ \boxed{ \rm{Mass \: \% = \frac{Mass \: of \: solute}{Mass \: of \: solution} \times 100}}}$

Plugging the given values:

⇒ Mass % of the Sol. = 50 g / 200 g × 100

⇒ Mass % of the Solution = 100 / 4 %

⇒ Mass % of the Solution = 25%

Hence the required concentration of salt in its solution in terms of its mass is 25%.

Note:

• As the mass of the solution is given here, we can directly calculate using formula.

• But when the mass of solvent is given, we need to add the mass of solute and mass of solvent to get the mass of solution.
