#1: in an icy glass of lemonade, which of the following is the solvent? a. lemon juice b. ice c. sugar d. water **my d. water is that right? : / @chmvijay : )

In a solution, there are two components that is solvent and solute. Solute is one that is dissolved and solvent is one in which is used for dissolving solute or it can be said that it is the which is used for dissolving. So in the icy glass of lemonade, there is a substance that is used for dissolving solute and it will be water as it is used for dissolving solute.

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.
