5.844 grams of NaCl is dissolved in 0.024 L to make a concentrated NaCl solution. Water is then added to the solution until the concentration becomes 0.011 M. Determine the final
volume of the solution (answer to 3 decimal places).

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.
