Posted by Anonymous on Friday, April 2, 2010 at 8:09am.

a) The element with the greatest density is osmium, which has a density of 22.6g/cm3. calculate the mass of 32.1 cm3 of osmium.
Answer: 22.6g x 32.1 = 725.46
Did I have right answer?

b) A team of students determined the density of a sample of wood to be 0.52g/cm3. A handbook of chemistry reported the density of 0.548g/cm3 for the same type of wood. what is the percent error of the students value?
anser:(0.548 - 0.52) / 0.548 x 100 = 5.1%
Can someone check my answer for me?
