A student measures a cube composed of an unknown substance. The mass was determined to be 112.8 g, and the volume 63 cm3. What is the density of the cube? a) 0.6 cm3/g b) 1.8 g/cm3 c) 0.6 g/cm3 d) 1.8 cm3/g

D

Explanation:

The formula to find the density of an object is mass/volume. You know the mass in this problem is 112.8 grams, and the volume is 63 cm^3. Now you can plug this information into the density formula as 112.8/63, which is about 1.8. Now you just add the cm^3/g and you have your answer.

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.
