Well, you should consult your periodic table for this...

And krypton, "Kr", with atomic number 36, has a molar mass of "83.798 g/mol".

That is by definition the mass of "Kr" gas atoms for every "1 mol" of krypton gas atoms. So, you already have your answer.

cancel"1 mol" xx "83.798 g Kr"/cancel"mol" = color(blue)ul"83.798 g Kr"

You should get to know your periodic table well enough that you can at least name every non-f-block element, and find it on the table during an exam.
