A reaction was performed in which 4.0 g of cyclohexanol was reacted with an acid catalyst to obtain 2.8 g of cyclohexene. calcul
ioda

Answer:

              %age Yield  =  85.36 %

Solution:

The Balance Chemical Reaction is as follow,

               C₆H₁₂O  +   Acid Catalyst    →    C₆H₁₀  +  Acid Catalyst + H₂O

According to Equation ,

              100 g (1 mole) C₆H₁₂O produces  =  82 g (1 moles) of C₆H₁₀

So,

                       4.0 g of C₆H₁₂O will produce  =  X g of C₆H₁₀

Solving for X,

                      X =  (4.0 g × 82 g) ÷ 100 g

                      X  =  3.28 g of C₆H₁₀   (Theoretical Yield)

As we know,

                     %age Yield  =  (Actual Yield ÷ Theoretical Yield) × 100

                     %age Yield  =  (2.8 g ÷ 3.28 g) × 100

                     %age Yield  =  85.36 %

Two moles of lithium has a mass of 13.88g. true or false
Dafna1 [17]
From the periodic table:
the mass of lithium = <span>6.941 grams
Since lithium is monoatomic, therefore, the molar mass of lithium = </span><span>6.941 grams

Now, we need to calculate the mass of two moles of lithium:
mass of two moles of lithium = 2 * </span><span>6.941 = 13.882 grams

Based on the above calculations, the answer is:
True</span>
