What are the units for density?

g/ cm^3 or g/mL

What unit should mass always be in for density?

grams

What unit should volume always be in for density?

mL or cm^3

Find the density of a block with the mass of 500g & 100cm^3.

D=M/VD= 500g/100cm^3D= 5 g/cm^3

Find the density of a block with the mass of 6kg & 30cm^3.

D=M/VD= 6000g/30cm^3D= 200 g/cm^3

Find the density of a block with the mass of 900g & 3m^3.

D=M/VD= 900g/300cm^3D=3 g/cm^3

Convert 50 F to C.
