Answer:
the mass of 25.50 mL of ethanol is approximately 20.12 grams.
Step-by-step explanation:
To calculate the mass of a liquid like ethanol, you'll need to know its density. The density of ethanol can vary with temperature, but at room temperature (20°C or 68°F), the density of ethanol is approximately 0.789 g/mL.
Mass = Volume × Density
Given:
Volume of ethanol = 25.50 mL
Density of ethanol = 0.789 g/mL
Mass = 25.50 mL × 0.789 g/mL
Mass = 20.12 grams
