Question

What volume of water has the same mass as 150 cm3 of gold?

Answer 1

Density of gold is 19.32
`(g)/(cm^(3))`

Given volume of gold = 150
`cm^(3)`

Calculating the mass of gold from volume and density:

Density =
`(Mass)/(Volume)`

Mass = Density * Volume

=
`(19.32g)/(cm^(3) ) *150cm^(3) = 2898 g`

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

Calculating the volume of 2898 g water:

`2898 g *(1cm^(3) )/(1 g) = 2898 cm^(3)`

Therefore, 2898
`cm^(3)` water has the same mass as gold of volume 150
`cm^(3)`
