A rock has a mass of 127 g and displaces 32.1mL of water. What is the density of the rock?

So, to get the density I do mass/volume so is this correct?

D = 127g/32.1mL = 3.956g/mL

Thank you! Do you think you could help me with one more problem?

a 1.00-L sample of tetrachloride has a mass of 1.58kg. What is the density of this substance in g/cm^3? Would I do 1.58kg/1.00L?

cwrw238 · Answer

yes

anonymous · Answer

So it's still 1.58. How do I put into g/cm^3?

cwrw238 · Answer

- because g/cm^3 is the same as kg/L
