1 mole = (6.022 x 10^23)
So 4.5 moles = (4.5) x (6.022 x 10^23)
4.5 x (6.022 x 10^23) = 2.7099 × 1024
(four point five times six point zero two two times ten to the twenty third)
For carbon tetrachloride, CCl4: 5 atoms.
For tetraiodoethene, C2I4: 6 atoms.
1.3 x 10^23
425 kA m-1
It is 218.33... (repeating) deg C.
Let us find moles first. Molarity = moles of solute/Liters of solution ( 750 ml = 0.750 Liters ) 0.375 M Na2SO4 = moles Na2SO4/0.750 Liters = 0.28125 moles Na2SO4 =================== 0.28125 moles Na2SO4 (142.05 grams/1 mole Na2SO4) = 39.95 grams Na2SO4 needed ---------------------------------------you do significant figures!
Sublimation is the transition of a substance from solid to gas without becoming a liquid first. To determine when this will happen you must find a phase diagram of the particular substance you are working it. There is something called the triple point, a particular pressure and temperature at which all three phases can technically exist. If you find a point below this, and a pressure and temperature at which a liquid wont exist whatever you are working with will go straight from solid to gas.
The answer is 1.35 moles.425 g of UF4 would be 1.35 moles.
Its 425
425 ÷ 25 = 17
There are: 425*60 = 25,500 seconds
