Final answer:
The mass of 53mL of ethanol with a density of 0.79 g/mL is calculated by multiplying volume by density, resulting in 41.87 grams.
Step-by-step explanation:
To find the mass of a volume of ethanol, given its density, you can use the formula: mass = volume × density. Given the density of ethanol as 0.79 g/mL and the volume as 53mL, the mass can be calculated as follows:
mass = 53mL × 0.79 g/mL
Now, multiply the density by the volume to get the mass:
mass = 41.87 g
Thus, the mass of 53mL of ethanol is 41.87 grams.
