The block of carbon contains
You need to determine the density of the carbon. Then use its density and volume to determine the mass of carbon in the block, then determine the number of moles of carbon in the block, and then determine the number of atoms. 1 mole of carbon is equal to
Carbon exists as different allotropes; amorphous carbon, graphite, diamond, fullerenes and others. Because graphite is more common, I'm going to use the density of graphite near room temperature, which is
Determine the mass of the carbon block.
(I will round to two significant figures at the end.)
Determine the moles of the carbon in the block.
Determine the number of atoms of carbon in the block.
To determine the number of atoms of carbon in the block, multiply the number of moles by
