Apure gold metal bar displaces 0.82 l of water. what is the mass in kilograms? (the density of gold is 19.3 g/cm^3)

Mass of gold bar is 15.8 kg

Explanation:

The gold metal bar displaces volume of water equal to volume of metal bar.

So, volume of gold metal bar = 0.82 L

We know that density is the ratio of mass to volume.

So mass of gold bar = (density of gold)(volume of gold bar) = ()g =15826 g

Now, 1 g = 0.001 kg

So mass of gold bar  = () kg = 15.8 kg

thats how its supposed to be

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
