They say that the sun will blow up after 200 billion years. IS THIS True or false?

MARKING BRAINLIST

True

Explanation:

The sun will become a red giant and increase in size. During that time, the earth will increase in 1 degree each day making it inhabitable to live

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.

let that person have a turn to speak : )
