Calculating the mass percentage of ethanol in a 20% ethanol solution
To calculate the mass percentage of ethanol in a solution, we need to know the density of the solution and the density of pure ethanol.
Density of the ethanol solution
The density of the ethanol solution is given as 0.977 g/mL.
Density of pure ethanol
The density of pure ethanol is given as 0.789 g/mL.
Calculating the volume percentage of ethanol in the solution
To calculate the volume percentage of ethanol in the solution, we can use the formula:
Volume percentage = (Density of ethanol solution - Density of pure solvent) / (Density of pure ethanol - Density of pure solvent) * 100
In this case, the pure solvent is water.
Using the given values:
Volume percentage = (0.977 g/mL - 1 g/mL) / (0.789 g/mL - 1 g/mL) * 100
= (-0.023 g/mL) / (-0.211 g/mL) * 100
= 0.109 * 100
= 10.9%
Calculating the mass percentage of ethanol in the solution
The mass percentage of ethanol in the solution can be calculated using the formula:
Mass percentage = (Volume percentage * Density of pure ethanol) / Density of ethanol solution
Using the given values:
Mass percentage = (10.9% * 0.789 g/mL) / 0.977 g/mL
= (0.0858 g/mL) / 0.977 g/mL
= 0.0879 * 100
= 8.79%
Therefore, the mass percentage of ethanol in the 20% ethanol solution is 8.79%.
To calculate the mass percentage of ethanol in a solution, we need to know the density of the solution and the density of pure ethanol.

= 0.109 * 100
= 10.9%

The mass percentage of ethanol in the solution can be calculated using the formula:
Mass percentage = (Volume percentage * Density of pure ethanol) / Density of ethanol solution
Using the given values:
Mass percentage = (10.9% * 0.789 g/mL) / 0.977 g/mL
= (0.0858 g/mL) / 0.977 g/mL
= 0.0879 * 100
= 8.79%
Therefore, the mass percentage of ethanol in the 20% ethanol solution is 8.79%.
