what is the mass of silver
Silver crystallises in a face centred cubic lattice with all atoms at the lattice points: The length of an edge of the unit cell was determined to be 408.6 pm. The density of silver is 10.5 g cm^-3. 1) calclulate the mass of a silver atom. 2) using the known value of the atomic mass of silver (107.87 u), calculate Avogadro's number. Thank you. Harriot
