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 4.00 cm x 3.20 cm? your show work.

296.448 g

Explanation:

Density:

we know that density of an object can be measured by dividing its mass to its volume.

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

D= density

m= mass

V= volume

Given data:

volume= 1.2 cm x 4.00 cm x 3.20 cm =15.36 cm3

density=  19.3 g/cm3

mass=?

Now we will put the values in the formula,

d=m/v

d x V= m

m = 15.36 cm3 x 19.3 g/cm3

m=296.448 g

so the mass of block of gold is 296.448 g

i would wait to see what he says back. then if he likes you back that's great go for it. if he doesn't than hopefully you can stay friends. if not i'm sure he's the one missing out.
