Answer: The mass of alcohol is 790 grams.
Explanation:
To calculate the mass of alcohol, we use the equation:
[tex]\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}[/tex]
Volume of alcohol = 1.0 L = 1000 mL (Conversion factor: 1 L = 1000 mL)
Density of alcohol = 0.79 g/mL
Putting values in above equation, we get:
[tex]0.79g/mL=\frac{\text{Mass of alcohol}}{1000mL}\\\\\text{Mass of alcohol}=790g[/tex]
Hence, the mass of alcohol is 790 grams.
