I'll tell you how to find it, but no answers

Explanation:

It's pretty simple. Your north and south points go first, then your east and west. You look at the dot, and trace your finger down the two lines to get your lattitude and longitude. From there, you just write it out. For example, G would be at (0,0) because the lines match up at 0,0 where the point is.

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.
