Answer: The percent yield of lithium chloride if a reaction starts with 20.0 g lithium hydroxide and yields 6.00 g lithium chloride is 17.2 %
Explanation:
The balanced chemical reaction is
To calculate the moles, we use the equation:
a) moles of
b) moles of
According to stoichiometry :
1 mole of produces = 1 mole of
Thus 0.83 moles of produce= of
Mass of
The theoretical yield of = 34.9 g
The experimental yield of ethanol = 6.00 g
Now we have to calculate the percent yield of ethanol.
Therefore, the percent yield is, 17.2 %
