What volume of gold would be equal in mass to a piece of copper with a volume of 101 ml? the density of gold is 19.3 g/ml; the density of copper is 8.96 g/ml?

We need 46,88 ml of gold to have the same mass as 101 ml of copper

Explanation:

First we have to calculate the mass of the piece of copper, remember that ml is a measure for volume, so we just have to solve the formula of density for mass:

Density=mass/volume

Mass=volume*density

And we instert the data that we knwo:

Mass=101*8.96

Mass= 904,96 grams

SO know that we now the mass of the copper piece, we can solve for volume in the formula of density to get how many mililiters of gold we need to have 904,96 grams:

Density=mass/volume

Volume=Mass/density

Volume= 904,96/19,3

Volume=46,88 mililiters

Seismic waves are the waves of energy caused by the sudden breaking of rock within the earth or an explosion. They are the energy that travels through the earth and is recorded on seismographs. ... Earthquakes radiate seismic energy as both body and surface waves.
