Problems with specific charge

  1. Oct 5, 2009 #1
    hi,
    im have a few trouble working out this question,

    Calculate the ratio of charge/mass in Ckg-1
    for the nucleus stated below

    236
    U
    92

    now i know the formula to use BUT im having trouble with calculating the figures for Charge and Mass.
    (i know that the charge is 1.6x10-19 )

    Please tell us the formula that you know you should use. Also, do you know the meaning of the numbers 236 and 92?

    the formula is - specific charge = charge / mass

    and the 236 is the nulceon number & 92 is the proton number

    Can you calculate the charge and mass from the nucleon number and proton number?
