Hey, Im in Honors chem, but my teacher went to Harvard and Yale so this stuff is hard

Gold can be hammered into extremely thin sheets called gold leaf.  A 450 mg piece of gold (density = 19.32gXcm-3) is hammered into a sheet measuring 2.4ft X 2.1ft

What is the average thickness of the sheet in meters?




Express the thickness determined wabove without exponentail notaation using an appropriate SI prefix

One part of the question i dont understand is what the density is???

COuld you show the work> so i could learn from this?  Thanks guyssss

This is how chemistry classes begin, you'll be given a value, and asked to convert units.  Write the problem out on paper, but don't do it typewriter fashion -- you're given the density of gold as:

19.32 g
-------
cm

Does writing it like that help you see how to work the problem?
