A reaction has a theoretical yield of 45.8 g. when the reaction is carried out, 37.2 g of the product forms. what is the percent
2 answers:
Answer:
81.22 %
Explanation:
Percent yield is the ratio of the actual yield to the theoretical yield. The higher is the actual yield the higher is the percent yield. Actual yield is always less than theoretical yield.
Given,
Theoretical yield = 45.8 g
Actual yield = 37.2 g
Percent yield = x 100
= x 100 = 81.22 %

Answer : The normal boiling point of ethanol will be, or
Explanation :
The Clausius- Clapeyron equation is :
where,
= vapor pressure of ethanol at
= 98.5 mmHg
= vapor pressure of ethanol at normal boiling point = 1 atm = 760 mmHg
= temperature of ethanol =
= normal boiling point of ethanol = ?
= heat of vaporization = 39.3 kJ/mole = 39300 J/mole
R = universal constant = 8.314 J/K.mole
Now put all the given values in the above formula, we get:
Hence, the normal boiling point of ethanol will be, or
