Romanian is spoken in ROMANIA... OK Brian then what do I listen to all day if not Romanian. They speak Romanian in Romania. They speak Italian in Rome although you will find those who speak English cause it is a touristy place. Considering that it's in ITALY, they mainly speak Italian. They only Speak Romanian in the brothels, and english at the cheap gift stores.
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
