Chloroform, CHCl3, has a density of 1.492 g/mL and a molar mass of 119.38 g/mol. (PLEASE DON’T ANSWER IF YOU CAN’T SHOW YOUR WORK OR GIVE AN EXPLANATION I’M REALLY TRYING TO LEARN HOW TO DO THIS) How much volume in mL does each mol of CHCl3 occupy? Hint: “Each mol” is
an exact amount and has infinite number of sig figs.

How many mol are there in 100.0 mL of CHCl3?

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.
