Answer 1

The density of pure gold (au) is 19.3 g/cm3. what is the mass of a block of gold that measures 1.2 cm x 5.00 cm x 3.20 cm? please show work.

Given: Density of pure gold = 19.3 g /cm^3

Measurement of block of gold =1.2 cm x 5.00 cm x 3.20 cm

To calculate : mass of gold

Formula used: Density = Mass / Volume

Volume = 1.2 cm x 5.00 cm x 3.20 cm = 19.2 cm^3

Mass of gold = Density X volume = 19.3 g /cm^3 X 19.2 cm^3  = 370.56 g
