We have used the CLEO II detector to study the multiplicity of charged particles in the decays of B mesons produced at the (Formula presented) resonance. Using a sample of (Formula presented) B meson pairs, we find the mean inclusive charged particle multiplicity to be (Formula presented) for the decay of the pair. This corresponds to a mean multiplicity of (Formula presented) for a single B meson. Using the same data sample, we have also extracted the mean multiplicities in semileptonic and nonleptonic decays. We measure a mean of (Formula presented) charged particles per (Formula presented) decay when both mesons decay semileptonically. When neither B meson decays semileptonically, we measure a mean charged particle multiplicity of (Formula presented) per (Formula presented) pair.
