Homework Help: Mass Spectrometry

  1. Apr 6, 2004 #1
    I have two molecules CO and N2 with masses 28.0106u and 28.0134u respectively.

    I need to determine the radius of curvature the spectrometer must have if the molecules are to be separated on film by 0.50mm.

    I don't even know where to begin to solve this. The only equation relating to it in the book is m=qB'r/v, where r=mv/qB'. But I don't have v or q or B'. Agghhh.

    Mco=28.0106u
    Mn2=28.0134u
    d=0.50mm
    r=?

    Would someone point me in the right direction? Thank you.

    How can I detemine if the following heteroatoms exist in a compound looking at a mass spectrum:
    S, Cl, and Br.
