Aprefume bottle is dropped in the conor of a room the odor of the prefume can be detected on the other side of the room which statement best describes this observation

Are there answers to this or o we just do it?

water is used to store them because it would keep the radiation from getting out in the open and causing harm to the workers

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
