Each mole of C2H6O will have 6.022 E23 molecules present. That means that in 3.25 moles, there are 1.957 E24 molecules present.
Avogadro's constant says that in one mole there are 6.022 E23 instances of something. So in 4.25 moles, there are 2.56 E24 molecules of CCl4.
Full formal set up.
1 mole CCl4 (4 mole Cl/1 mole CCl4)(6.022 X 1023/1 mole Cl)(1 mole Cl atoms/6.022 X 1023)
= 4 moles Cl atoms
==============
1 mol of Cl2, weighs 70.1 g.
So 4.5 mol of Cl2 weighs 315.45 g
Multiply it by Avogadro constant. There are 7.5275*10^23 molecules
1 mole CO2 = 6.022 x 1023 molecules CO2
3.25mol CO2 x (6.022 x 1023 molecules CO2)/1mol CO2 = 1.96 x 1023 molecules CO2
3.25* (6.022* 10^23)= (1.96*10^24)
The answer is 3,683 molecules.

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.
