Welcome my friends, thank you very much, I love you so much, and free points to all of you. Sorry, the two of you, but I love you all

Hi thx

Explanation:

Can ya please mark as brainliest

thanks for free points

well how r u

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.

d.) circle motion requires a force to give it a centripetal acceleration.
