  1. Calculate the new Capacitance, C', by multiplying the original C by the dielectric constant of Pyrex, k.

    The added charge will be V*(C'-C)=
    = (k-1)C V

  2. According to one website I found, "The dielectric constant of Pyrex is relatively low, in the range of 4.0 to 6.0" They may have provided you with a value already.
