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
Simply add each mass contribution together to find the total. Molecular mass of K3Fe(CN)6 = 117.30 g/mol + 55.85 g/mol + 72.06 g/mol + 84.06 g/mol. Molecular mass of K3Fe(CN)6 = 329.27 g/mol. Step 4: Find the mass percent composition of each element. To find the mass percent composition of an element, divide the mass contribution of the element by the total molecular mass.
