The volume of 495 g of ethanol can be calculated using its density. The density of ethanol at room temperature (25°C) is approximately 0.789 g/mL.

To calculate the volume, we can use the formula:

Volume = Mass / Density

Substituting the given values into the formula, we get:

Volume = 495 g / 0.789 g/mL = 627.6 mL

Therefore, the volume of 495 g of ethanol is approximately 627.6 mL.
