Question

The density of water is 1.00 g/cm3. The density of ethanol is 0.80 g/cm3. What is the volume of ethanol, in cm3 that has the same mass as 100 cm3 of water?

Answer 1

1.00 g/cm3

Step-by-step explanation:

Answer 2

Step-by-step explanation:

Given that,

The density of water is 1 g/cm³

The density of ethanol is 0.8 g/cm³

We need to find the volume of the ethanol that has the same mass as 100 cm³ of water.

Density=mass/volume

For water,

`d=(m)/(V)\\\\m=dV\\\\m=1\ g/cm^3* 100\ cm^3\\\\m=100\ g`

For ethanol,

`d=(m)/(V)\\\\V=(m)/(d)\\\\V=(100\ g)/(0.8\ g/cm^3)\\\\V=125\ cm^3`

Hence, 125 cm³ of ethanol has the same mass as 100 cm³ of water.
