Answer:

#"There are 0.50 moles precisely"#.

Explanation:

The molar mass of #""^12C# is #12.0*g*mol^-1#.

What does this mean? It means that #N_A" (Avogadro's number "=6.022xx10^23)"# #""^12C# atoms have a mass of #12.0*g#.

You have specified #6.0*g#.

Thus #(6.0*g)/(12.0*g*mol^-1)# #=# #0.50*mol#.
