What we have to do if our frnds cheats us ?​

We should tell them the truth on which they have cheated and give them to do of their own choice and we should think positive and be happy .we should be smiling by our heart not for them only for is and our family .

hope it is helpful to you ☺️

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.
