Mercury has a specific gravity of 13.6. how many milliliters of mercury have a mass of 0.35 kg

The formula for specific gravity is:

where is the density of the substance and is the density of water.

The density of water, =

Substituting the values in above formula we get,

The formula of density is:

The density of mercury is

The mass of mercury is

Substituting the values in density formula:

The amount, in milliliters, of mercury that will have a mass of 0.35 kg would be 25.74 mL.

If the specific gravity of mercury is 13.6, the density can be obtained such that:

Density of mercury = specific gravity of mercury/density of water

The density of water is 1 g/mL. Thus:

Density of mercury = 13.6/1

                              = 13.6 g/mL

Also; density = mass/volume

       volume = mass/density

                    = 350/13.6

                       = 25.74 mL

Thus, the number of milliliters of mercury that will have a mass of 0.35 kg would be 25.74.
