HEY EVERYONE I NEED YOUR OPINIONS I MIGHT ME GETTING FLORENCE BY MILLS ON CHRISTMAS, IF U DONT KNOW WHAT IT IS ITS A MAKEUP AND SKINCARE BRAND MY MILLIEBOBBYBROWN (eleven from stranger things) SO WHICH ONE SHOULD I GET?

⬇️⬇️⬇️

umm just get it

millie Bobby brown is fine btw

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.

the answer is 0.8m.
