The percent yield represents that the efficiency of a reaction.

It represents how much times we have achieved the target yield from a particular reaction

The relation between theoretical yield, measured yield and percent yield is

percent yield = \frac{measuredyieldX100}{theoreticalyield}

for the given reaction

percent yield = \frac{88.3X100}{93.7}=94.23%

Answer: 94.23%

Cinnamon owes its flavor and odor to cinnamaldehyde (C9H8O). Determine the boiling point elevation of a solution of 92.7 mg of c
Flauer [41]

Answer:

The boiling point elevation is 3.53 °C

Explanation:

∆Tb = Kb × m

∆Tb is the boiling point elevation of the solution

Kb is the molal boiling point elevation constant of CCl4 = 5.03 °C/m

m is the molality of the solution is given by moles of solute (C9H8O) divided by mass of solvent (CCl4) in kilogram

Moles of solute = mass/MW =

mass = 92.7 mg = 92.7/1000 = 0.0927 g

MW = 132 g/mol

Moles of solute = 0.0927/132 = 7.02×10^-4 mol

Mass of solvent = 1 g = 1/1000 = 0.001 kg

m = 7.02×10^-4 mol ÷ 0.001 kg = 0.702 mol/kg

∆Tb = 5.03 × 0.702 = 3.53 °C (to 2 decimal places)

You have 255 mL of a 1.5 M solution, how much liquid do you need to BOIL AWAY to increase the molarity to 2.5 M?
Lera25 [3.4K]

Answer:

102ml

Explanation:

  1. by using the dilution formulae and then you slove for the second volume by making it subject of the fomular
  2. when you get it you then subtract the final volume that you got from the initial volume because they asked from the question what liquid do u need to boil away
