Answer:

The density of the  bar of gold is  19.32 grams per cubic centimeter .

Step-by-step explanation:

Formula

[tex]Density = \frac{Mass}{Volume}[/tex]

As given

A bar of gold has a volume of 722 cubic centimeters and weighs 13.949 kilograms.

As 1 kilogram = 1000 gram

Than convert 13.949 kilograms into grams.

13.949 kilograms = 13.949 × 1000 grams

                             = 13949 grams

Mass = 13949 grams

Volume = 722 cubic centimeter

As put in the formula

[tex]Density = \frac{13949}{722}[/tex]

Density = 19.32 grams per cubic centimeter (Approx)

Therefore the density of the  bar of gold is  19.32 grams per cubic centimeter .
