Question

 what is the answer to this problem. i need help to check my answers.

Answer 1

density = mass / volume ⇒

 

volume = mass / density = (6.4 g) / (2 g/ml) = ? ml

Answer 2

Density = Mass/Volume

 

Volume * Density = Mass

 

Volume = Mass / Density

 

            = 6.4 g divided by 2 g/ml

 

           = 3.2 ml
