the mass of copper metal is 6.342g and the density of copper is 7.6g per cm/cube what is its volume

Question

Answer 1

Density = mass/volume = 7.6 g/cm³

6.342 g x 1 cm³/7.6 g = 0.834 cm³ = 0.83 cm³ (to 2 significant figures)

 

Answer 2

D = M/V  ---> V* D = M  -----> V = M / D

 

 

 

V = 6.342  / 7.6  

 

   = 0.83447368421052632... 

 

 

Now, for resolving the measurements:

 

 grams /  ( grams/cm^3)

 

the grams cancel and cubic centimeters go to the top

 

 

0.83447368421052632.... cm^3
