We obtain the baryon number density, n, and the excess contribution to the pressure, \mathrm\ensuremathΔP, at finite chemical potential, \ensuremathμB, and temperature, T, by resumming the Taylor series expansion in a lattice computation with lattice spacing of 1/(4T) and two flavors of quarks at three different quark masses. The method proceeds by giving a critical \ensuremathμB and limits on the critical exponent, and permits reliable estimations of the errors in resummed quantities. We find that n and \mathrm\ensuremathΔP are insensitive to the quark mass. We also report the bulk isothermal compressibility, \ensuremathκ, over a range of T and \ensuremathμB.
