Solution:
Given:
Volume fraction of ethanol in solution = 20%
Density of solution = 0.997 g/mL
Density of ethanol = 0.789 g/mL
Calculations:
Let us consider 100 mL of the solution. Then, the volume of ethanol in the solution would be 20 mL (20% of 100 mL).
The mass of the solution can be calculated using the density formula:
Density = Mass/Volume
Mass = Density x Volume
Mass of 100 mL of solution = 0.997 g/mL x 100 mL = 99.7 g
The mass of ethanol can also be calculated using its density and volume:
Mass of ethanol = Density of ethanol x Volume of ethanol
Mass of ethanol = 0.789 g/mL x 20 mL = 15.78 g
The mass percent of ethanol solution is the mass of ethanol divided by the mass of solution, multiplied by 100:
Mass percent of ethanol solution = (Mass of ethanol/Mass of solution) x 100
Mass percent of ethanol solution = (15.78 g/99.7 g) x 100 = 15.8%
Answer:
The mass percent of the ethanol solution is 15.8%.
Given:
Volume fraction of ethanol in solution = 20%
Density of solution = 0.997 g/mL
Density of ethanol = 0.789 g/mL
Calculations:
Let us consider 100 mL of the solution. Then, the volume of ethanol in the solution would be 20 mL (20% of 100 mL).
The mass of the solution can be calculated using the density formula:
Density = Mass/Volume
Mass = Density x Volume
Mass of 100 mL of solution = 0.997 g/mL x 100 mL = 99.7 g
The mass of ethanol can also be calculated using its density and volume:
Mass of ethanol = Density of ethanol x Volume of ethanol
Mass of ethanol = 0.789 g/mL x 20 mL = 15.78 g
The mass percent of ethanol solution is the mass of ethanol divided by the mass of solution, multiplied by 100:
Mass percent of ethanol solution = (Mass of ethanol/Mass of solution) x 100
Mass percent of ethanol solution = (15.78 g/99.7 g) x 100 = 15.8%
Answer:
The mass percent of the ethanol solution is 15.8%.
