Using the distance from the average primary vertex to reconstructed secondary vertices in jets, samples of events with b purity varying from about 13% to 89% have been selected. The charged particle multiplicity in the hemispheres opposite those containing these jets has been studied as a function of the b purity of the events. Extrapolating to 0% and 100%b purity, values of the hemisphere charged particle multiplicity in Z0→ {Mathematical expression} events and in non- {Mathematical expression} events have been measured to be {Mathematical expression} The first error is statistical, the second systematic and the third is a common systematic error. The difference in charged particle multiplicity between b quark events and light (u, d, s) quark events has been measured and found to be {Mathematical expression} The result is compared to the predictions of MLLA QCD calculations. By studying the impact parameter distributions of charged particles in the hemispheres opposite these jets, the charged particle decay multiplicity of B hadrons from Z0 decay, including particles from Ks 0 and Λ decay, has been measured to be {Mathematical expression} From the mean momentum of these decay products and separately from the number of primary charged particles per b event, the average xE of b flavoured hadrons has been measured to be {Mathematical expression}
