When a red juice mix is added to water, it dissolves. How do you know this? When combined, the juice mix reacts with water to make a new substance.
When combined, the juice mix settles to the bottom of the glass.
When combined, the water remains colorless, and you can only see one part.
When combined, the water turns a red color, and you can only see one part.

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.

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .
