Chem question? 2.	A block of material has a volume of 2 m3. It has a mass of 1 × 104 kg. Calculate the density of the material sample and express your results in g/cm3 with appropriate scientific notation.

anonymous · Answer

density = mass/volume; 104 kg / 2 m^3 --> 52 kg / m^3.

1 m^3 must be turned into cm^3. because of the cubes, 1m^3 is not 100 cm^3.

anonymous · Answer

1m^3 is not 10cm^3*

because of the square and cubic relations like illustrated:
|dw:1380660410712:dw|

anonymous · Answer

I believe 1m^3 would be 1000cm^3

anonymous · Answer

52 kg / 1000 cm^3

"kilo"gram -> one thousand gram

52 000 / 1000 cm^3     --------> 52g/cm^3
