Completing a Mole Ratio Table
An experiment was carried out in which Alcohol A (C7H16O) was treated with concentrated HCl and converted to the corresponding alkyl chloride.
Enter the missing information to complete the mole ratio table below and calculate the percentage yield.
Substance | Molar mass | Density / g cm^3 | Mass / g | Volume / cm^3 | Moles | Limiting reagent
Alcohol A | 116 | 0.835 | 15 | | |
12M HCl | | | | 28 | |
Alkyl chloride product | | | 14.17 | | |
The expected moles of product are
Percentage yield = ( ) / ( ) x 100 = %
The density of a liquid determines whether it is the top or bottom layer in a separatory funnel.
This means that the less dense layer would be the top layer.
The density of an organic solvent is 1.45 g/cm^3
The density of aqueous (water-based) solutions is 1.01 g/cm^3
The organic solution and the aqueous solution are both poured into a separatory funnel.
They are shaken together to perform an extraction and then the layers are separated.
The top layer is placed in a beaker and the bottom layer is placed in a conical flask.
This means that the beaker contains the aqueous solution.
