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
No one single atom of the element has the given atomic weight because the atomic weight of the element is an average, specifically called a weighted average. Given the previous paragraph, here is a question you could be asked: Silver has an atomic mass of 107.868 amu. Does any atom of any isotope of silver have a mass of 107.868 amu? Explain why.
