You might make use the neat molar mass calculator at thisperiodictable.com

kindly coded by Dr Kaisa Helttunen and Prof Heikki Kainulainen from the
University of Jyväskylä in Finland.  Simply key in the correct chemical formula using atomic symbols from the Periodic Table grid and conveniently it will check your answers for you.

You will notice that any formula you type in is displayed using so-called Hill notation, an idea
published in JACS by Edwin A. Hill (Journal of the American Chemical Society  1900, 22, 8, 478-494)  and widely used since 1906 (
