Explanation:
you make use of the formulas
amount(mol) = number of particles ÷ 6.02 × 10^23
and
mass(g) = amount(mol) × molar mass
The given question is incomplete. The complete question is ;
Ammonia gas can be prepared by the following reaction:
In an experiment, 27.6 g of ammonia gas, , is produced when it was predicted that 50.2 g of
would form.
What is the theoretical yield of ? What is the actual yeild of
? What is the percent yeild of
?
Answer: a) 50.2 g
b) 27.6 g
c) 5.0 %
Explanation:
a) Theoretical yield is defined as the amount of the product that is possible in the reaction.
Theoretical yield of = 50.2 g
b) Experimental or actual yield is defined as the amount of the product that is actually formed in the reaction.
Experimental yield of = 27.6 g
c) Percentage yield is defined as the ratio of experimental yileld to the theoretical yield in terms of percentage.
Hence percentage yield for the reaction is 55.0 %.
