The density of osmium (the densest metal) is 22.57 g/cm3. If a 1.00-kg rectangular block of osmium has two dimensions of 4.00 cm x 4.00 cm, calculate the third dimension (in cm) of the block. Watch significant figures.

Solutions

Expert Solution

Density is calculated by Mass/Volume

Volume = a*b*c cm3

S.F. = Significant Figure

the 3rd dimension is 2.77 cm ( significant figures keep remember)

The density of a 10 kg cube of silver is 10.5 g/cm3. What would the density of a 5 kg cube of silver be? I thought the answer would be 5.25 g/cm^3 because m1/m2=p1/p2 so 10kg/5kg=10.5 g/cm^3/ x and you solve for x. But this is coming up as wrong and I don't know why, do i need to convert the kg to g???
