what are three main advantages of studying objects at different wavelengths of radiation?
part 2 is the green house effect operating in earth's atmosphere or harmful? give examples. what are the consequences of an enhanced greenhouse effect?

oh it is true if thats what you are asking

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.

a is the answer to this question

explanation:

0.88m hope i am correct : )
