Project #789 - Solid state Physics (Doping)

Please explain to me how too do the following question.I'm a little bit confused on the carrrier density and the carrier concentration

2 g of boron (B) has been added to 30 kg of pure silicon (Si). Calculate (a) the carrier density and (b) the electrical resistivity of the resulting extrinsic semiconductor in the saturation regime. Si has a diamond cubic structure with 8 atoms per unit cell and a lattice constant of 0.5431 nm. The atomic weights of Si and B are 28.1 and 10.8, respectively. The electron and hole mobilities in Si are 0.135 and 0.048 m2/Vs respectively.
