Isotope Abundances-*delete me*

The mass of a sodium atom is known to be 1.920 times that of a C-12 atom. Find the atomic mass of a sodium atom.

Please do it in steps because I'm confused. How do i know the size of a C12 atom.

Also, if something was 0.340% you wouldn't have to convert it to decimals right?

What is the definition of a mole? What is the mass of one atom of 12C?

As to the second question, I'm not completely sure what you're trying to answer, so can't offer any real advice other than to say maybe
