What’s the difference between climate change and global warming

Global warming is talking about the longer time warming of the planet, like breaking ice. Climate change is very similar, but refers to more changes that are happening to our planet, like wildfires.

Hope this helped!

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.

i'm assuming that the correct answer is indeed the first one/ "a"..
