The formula for benzene is C6H6. Figure the molar mass of benzene to the nearest gram?
The molar mass of benzene is 78 g.
What is the mole fraction of each component if 3.9g of benzene is dissolved in 4.6g of toluene?
The molar mass of benzene (C6H6) is 78.11 grams per mole. The molar mass of toluene is 92.14 grams per mole. Mole fraction of a solute equals moles of solute divided by the moles of solute plus the moles of solvent. .5 of each is the mole fraction.
The density of benzene at 15 is 0.8787 Calculate the mass of 0.1900 of benzene at this temperature?
The density of benzene at 15 is 0.8787 . Calculate the mass of 0.1800 of benzene at this temperature.
What is the mass percent composition of an element in a molecule?
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
What the mass percent composition of an element in a molecule?
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
Calculate the mole fraction of benzene in solution containing 30 percent by mass in carbon tetrachloride?

Thee formula for benzene is C6H6. Figure the molar mass of benzene to the nearest gram?
The molar mass of benzene is 76,11 g.
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 mass percent composition of an element in a molecule?
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
What is the percent composition of hydrogen in benzene?
The formula shows that the compound contains 8 hydrogen atoms per molecule, of which the gram molecular mass is 46.07. Each hydrogen atom has a gram atomic mass of 1.00794. Therefore, the percent by mass of hydrogen in the compound is 100[8(1.00794)/46.07] or 17.50 %, to the justified number of significant digits. (The value "8" is exact.)
What the mass percent composition of an element in a molecule?
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
How many grams are there in one moleof benzene?
Benzene has a chemical formula of C6H6 This has a molar mass of 78. So one mole has a mass of 78 grams
