1.

A solution contains 50 ml of alcohol mixed with 150 ml of water .Calculate the concentration of the solution.​

Answer»

Answer:

  • 25% is the required concentration of SOLUTION.

Explanation:

According to the Question

It is given that ,

  • Volume of solute (alcohol ) = 50ml
  • Volume of Solvent (water) = 150ml

we have to calculate the concentration of the solution .

FIRSTLY we calculate the volume of solution .

= volume of solute + Volume of solvent

= 50ml + 150ml

= 200m/

As we know that the concentration in f solution is CALCULATED by

•Concentration = Volume of Solute/Volume of solution × 100 %

PUTTING the value we get

➻ Concentration of Solution = 50/200 × 100 %

➻ Concentration of Solution = 5000/200 %

➻ Concentration of Solution = 50/2 %

➻ Concentration of Solution = 25%

  • Hence, the concentration of the solution is 25%
