Weight/volume of 1*10^43 carbon atoms,answer

Post  Thesci3141 on Mon Jan 03, 2011 1:12 pm

You will have 1.99*10^20 grams of carbon. As for the volume, it depends on the form of carbon we have because of the different densitys . Amorphous carbon: 1.8-2.1 g/CM3 : graphite:2.25 g/CM3 : Diamond: 3.52 g?CM3. Just for the fun of it I used Diamond in my calculations for the radius of a sphere that will occupy this many grams of carbon. I come up with a sphere of 14.83 miles radius. Quite a large diamond. Will someone else calculate this and check me please.

I got 14.8 miles.

1.99 x 1020 g x 1 cm3/ 3.52 g x 1 m3/ 106 cm3 = 5.65 x 1013 m3

V=4/3πr3

5.65 x 1013=4/3πr3

r= 23,800 m = 14.8 miles
