A 1.00 carat pure diamond has a mass of 0.2 grams. How many carbon atoms are there within this diamond?

Answer 1

Owen Ambrose

#"Number of carbon atoms":#

#=# #(0.2*g)/(12.01*g*mol^-1)xxN_A" carbon atoms mol"^-1#

#=# #??" carbon atoms"#

#N_A# #=# #"Avogadro's number"# #=# #6.022xx10^23*mol^-1#.

We know that in a #12.00*g# mass of #""^12C# atoms there are #N_A# #"carbon atoms"# precisely.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
