A solution contain 40 centimetre cube of alcohol mixed with 150 cm cube of water calculate the concentration of the solution
Total volume of solution:
= 40 cc + 50 cc
= 90 cc
Concentration of alcohohol:
= (volume of alcohol / total volume) × 100%
= _____ % alcohol
To calculate the concentration of the solution, we can use the formula:
Concentration = (volume of solute / volume of solution) x 100%
In this case, the solute is alcohol and the solution is a mixture of alcohol and water.
Given:
Volume of alcohol (solute) = 40 cm^3
Volume of water + alcohol (solution) = 150 cm^3
To find the concentration:
Concentration = (40 cm^3 / 150 cm^3) x 100%
Concentration = 0.267 x 100%
Concentration = 26.7%
Therefore, the concentration of the solution is 26.7%.
To calculate the concentration of the solution, you need to know the amount of solute (alcohol) and the total volume of the solution.
In this case, the amount of alcohol in the solution is 40 cm³, and the total volume of the solution is obtained by adding the volume of alcohol and the volume of water, which is 150 cm³.
Therefore, the concentration of the solution can be calculated using the following formula:
Concentration = (Amount of Solute / Total Volume) x 100
Substituting the values:
Concentration = (40 cm³ / (40 cm³ + 150 cm³)) x 100
Concentration = (40 cm³ / 190 cm³) x 100
Concentration ≈ 21.05%
So, the concentration of the solution is approximately 21.05%.
