Are all cells the same? Give examples

100% no.

Blood cells and white cells, for example, have different colors.

White cells are larger with not much of them while blood cells are opposite.

They are in our body

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

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

will have a gram-molecular weight of 352g.

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
