Question

calculate the concentration of a solution in volume percent made when 56 g of water is mixed with 0.17 L of ethanol​

Answer 1

Answer:

To calculate concentration by volume, first convert into volumes.

Volume of ethanol = 0.17l

Volume of water = 56g/(1g/cm³) = 56 ml = 0.056l

(taking density of water = 1g/cm³)

Total volume of solution = 0.17 + 0.056 = 0.226l

Concentration of ethanol = \frac{volume of ethanol in solution}{volume of total solution}volumeoftotalsolutionvolumeofethanolinsolution  × 100

⇒ Concentration = \frac{0.17}{0.226}0.2260.17  × 100

⇒Concentration = 75.22%
