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
âAn atomic weight (relative atomic mass) of an element from a specified source is the ratio of the average mass per atom of the element to 1/12 of the mass of an atom of 12 C.â The mass of the most abundant isotope contributes more towards the atomic weight. For example, Cl-35 natural abundance is 75.76%, and Cl-37 abundance is 24.24%. The atomic weight of Chlorine is 35.453 (amu), which is closer to the mass of the Cl-35 isotope.
