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
Atomic Weight Calculation Example. If chlorine has two naturally-occurring isotopes where: Cl-35 mass is 34.968852 and fract is 0.7577. Cl-37 mass is 36.965303 and fract is 0.2423. atomic weight = massa x fracta + massb x fracb. atomic weight = 34.968852 x 0.7577 + 36.965303 x 0.2423. atomic weight = 26.496 amu + 8.9566 amu.
