The density of gold is 19.33 g/cm3. If a slab of gold is found to have a total volume of 0.549 cm3, how much does the slab weigh?

Question

The density of gold is 19.33 g/cm3. If a slab of gold is found to have a total volume of 0.549 cm3, how much does the slab weigh?

Answer 1

m = ρV

 

Plug in 

 

ρ = 19.33 g/cm³

V = 0.549 cm³

 

and get m in grams.

 

W = mg

 

Plug in m from above, and 

 

g = 981 cm/s²

 

to get W in dynes; or convert m to kg, and plug in 

 

g = 9.81 m/s²

 

to get W in newtons.

Answer 2

Desnity = Mass/Volume

 

Density * Volume = Mass

 

19.33 g/cm^3 * 0.549 cm^3 = Mass

 

10.61217 g = Mass
