A solution contains 50ml of alcohol mixed with 150ml of water. Calculate the concentration of solution
Answers
Answer:
25%
Explanation:
Volume of solute (alcohol) = 50ml
Volume of solvent (water) = 150ml
Volume of solution ( water + alcohol )
= 50 ml + 150 ml = 200 ml
concentration = volume of solute/ volume of solvent multiplied by 100
=50/200 multiplied
= 25%
Concept introduction:
Concentration of a solution is considered as the measurement of the exact volume of solute which is dissolved in a particular amount of solvent. In this context, concentration refers to mass of a solute and the total volume of the solvent.
Given:
We have been given the alcohol concentration and amount present in a solution along with the quantity of water which is mixed with alcohol.
To find:
We need to fins the concentration of the solution.
Solution:
As per the question,
Volume of alcohol: 50 ml
Volume of water: 150 ml
Therefore, total volume of the solution: 150+50=200 ml
We know that,
concentration= 9volume of solute/volume of solvent)*100
=50/200
=1/4=25%
Final answer:
The concentration of the solution is 25%
