Using three- and four-body decays of D mesons produced in semileptonic b-hadron decays, precision measurements of D meson mass differences are made together with a measurement of the Dº mass. The measurements are based on a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected in pp collisions at 7 TeV. Using the decay Dº → K + K - K - π +, the Dº mass is measured to be M(Dº)=1864.75± 0.15(stat)± 0.11(syst) MeV/c2. The mass differences M(D+)-M(Dº=4.76± 0.12(stat)± MeV/c 2. M(Ds +)-M(D+)=98.68± 0.03(stat)± 0.04(syst) MeV/c2 are measured using the Dº → K + K - π + π - and Ds + to K+K -π+ modes.
