Question

Which has a greater volume, 10 grams of water or 10 grams of acetone?

Answer 1

Density is defined as the ratio of mass to the volume.

Density =
`(Mass)/(Volume)` (1)

Mass of water = 10 grams

Mass of acetone = 10 grams

Density of water = 1
`(g)/(cm^(3))`

Density of acetone = 0.7857
`(g)/(cm^(3))`

Put the value of density of water and its mass in equation (1)

1
`(g)/(cm^(3))` =
`(10 g)/(volume)`

Volume of water = 10
`cm^(3)`

Put the value of density of acetone and its mass in equation (1)

0.7857
`(g)/(cm^(3))` =
`(10 g)/(volume)`

Volume of acetone = 12.72
`cm^(3)`

Thus, volume of acetone is more than volume of water because the density of acetone is lower.
