A solid piece of gold has a mas of 1.15 kg and a volume of 3.8 deciliters. What is the density of the object?

Question

 Part of my post labs questions and it driving me nuts trying to answer.

Answer 1

Density is simply mass divided by volume or m/v.  So, here you have 1.15 kg/3.8 deciliters = 0.303 kg/dL = density.

However, most chemists prefer density in units of g/ml or kg/L, etc.  So, to convert to the more general g/ml, you must convert kg to g and dL to ml.

0.303 kg x 1000 g/kg = 303 g

1 dL x 100 ml/dL = 100 ml

Density in g/ml = 303 g/100 ml = 3.03 g/ml
