What volume in cubic centimeters would be occupied by 7.96 kg of osmium? The density of osmium (the densest metal) is 22.57 g/cm3?
Units are important! 7.96 kilograms- but density is given in grams per centimeters cubed...

The first thing to do in this problem is convert the given information so that everything has the same units (g and cubic centimeters).
7.96 kg has 7960 grams in it (7.96 kg x 1000 g) so the osmium given is 7960 grams.
D = M/V is the formula for density but we're looking for V whereas we have the density and the mass already. Through algebra, we can rewrite the formula for volume as:
V = M/D
By plugging in 7960 for mass and 22.57 for density, we get the answer of about 352.68.
If we look at significant digits, the answer to your question is: 353 cubic centimers.

Yeah but 1 kg = 1000 gms or 1 gm = 0.001 kg. SO volume = 7.96/(0.02257) cm^3
