What is the percent by mass of benzene in a solution containing 14.2 g of bezene in 28.0 g of carbon tetrachloride?
If it is pure benzene and CCl4 your answer is; % Benzene = (m Benzene)/(m Total)*100 = 14.2 / (14.2 + 28) * 100 = 33.65 % If the solution is benzene and CCl4 dissolved in water or another solvent, the answer depends entirely on how much solvent you have.
What is the molarity of pure liquid benzene?
Molarity is a concentration unit of solutions, pure benzene is not a solution so this term is meaningless for a pure liquid. In other words: Molarity of a solution is a numerical way of saying exactly how much solute is dissolved in a solvent .Molarity is equal to the moles of solute divided by the liters of solution. Molarity of a solution can be calculated by using the following formula: M= moles of solute/liters of solution
Explain why a solution of HCl in benzene does not conduct electricity but in water it does?
In a solution of HCL and water, H20 has stronger polar bonds toward HCL causing it to disassociate into H+ and Cl- Ions. Benzene doesnt have those types of polar bonds so HCL doesnt dissolve as readily. (salt and water1 vs. oil and water2.)(the second water acting as benzene would.)
What is the boiling point of a 2.47 molal solution of napthalene in benzenethe boiling point of benzene is 80.1?
the boiling point of platnium is 2500c
Which is the upper layer between water and benzene?
Benzene
A solution is prepared by dissolving 16.2 g of benzene in 282 g CCL4 find molarity of thesolution density of the solution is 0.92gml?
0.736 i think good luck
Will Na2SO4 and benzene form a solution?
no
Is benzene an electrolyte in an aqueous solution?
Benzene, being a covalent compound is not soluble in water. So a solution of benzene in water is absurd. However in answering your question I would say that, as benzene is not soluble in water it does not function as an electrolyte. Some more improvement would be that benzene itself is not an electrolyte.
Why is benzene no longer used to extract caffeine from plants?
your momma destroyed the plants

Does Benzene and water form a good solution?
No benzene is extremely hydrophobic and sits like an oil on top of the water.
Calculate the mole fraction of benzene in solution containing 30 percent by mass in carbon tetrachloride?
calculate the mole fraction of benzene in solution containing 30% by mass in carbon tetra chlorid
Acidified potassium permanganate reaction with toluene equation?
toluene is benzene with CH3 reacting this with KMnO4 in acidic solution will produce a benzene with a carboxylic acid (CH3 will be oxidized)
A solution is made by dissolving 0.551 mol of nonelectrolyte solute in 899 g of benzene. Calculate the freezing point Tf and boiling point Tb of the solution. Constants may be found here.?
∆T = imK∆T = change in temp; i = van't Hoff factor (1 for non electrolyte); m = molality; K = constantm = 0.551 moles/0.899 kg = 0.612Look up the Kf and Kb for benzene and substitute in above equation and solve for ∆T.Add this to the normal b.p. and subtract it from the normal f.p. to get new b.p. and f.p.
Aqueous solution of gaseous HCl is acidic but solution of HCl gas in benzene has no acidic property?
This is because of the polarity of the solvents. Aqueous solution (H2O) is very polar and will produce H+ ions when HCL is added, thus resulting in a acidic solution. On the other hand, benzene, a nonpolar solvent will not produce H+ ions and no acidic properties.
The freezing point of benzene is 5.5C What is the freezing point of a solution of 5.00 g of naphthalene C10H8 in 444g of benzene Kf of benzene 4.90Cm?
New Temperature= 5.5 C - .431 C = 5.069 C Theres the answer, now figure out how to do it... -Greg
