I know that the density of pure gold is 19.32 gm/cm^3 so 1 kg/19.32 gm/cm^3= 0.05175 ?

I have come along way with this problem and feel like I am close, but now I need help.

How do I get kg and gm to cancel?

How do I get this to be 51.8cm^3?

**Damon**, Friday, November 21, 2008 at 5:40pm1 kg = 1,000 grams

so

1,000 grams (1 cm^3/19.32 grams) = 51.8 cm^3

always multiply by a ratio that is the same top and bottom but in different units so that the units cancel

for example if I were given this the other way as 51.8 cm^3 of gold, then

51.8 cm^3 (19.32 grams/1cm^3) = 1000 grams because the cm^3 cancels top and bottom and we are left with grams.
