The density means that the mass divided by the volume with the formula: density = mass/volume. So volume=mass/density. Under same temperature, the volume=15.5/0.789=19.6 cm3=19.6 ml.

Answer:

Volume of ethanol = 19.6 cm3

Explanation:

Given:

Density of ethanol = 0.789 g/cm3

Mass of ethanol = 15.5 g

To determine:

The volume of ethanol corresponding to the given mass

Formula:

Density of a substance is essentially the mass occupied by it per unit volume

[tex]Density = \frac{Mass}{Volume}[/tex]

Based on the above equation:

[tex]volume = \frac{Mass}{Density} =\frac{15.5 g}{0.789g/cm3} =19.6 cm3[/tex]
