How is the image that you see through the lens different from images that you see using your eye?

the image you see through a lense is different then you see with your eye because the lense is stained a certain way to prevent exposure to dangerous things because it filters it out, also its because the lense were made a special way with certain chemicals that also produce that effect, meaning that the color spectrum is different when you look at certain things with a lense.

Explanation:

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.
