Answer:
Two.
Explanation:
Hello!
In this case, considering the attached picture wherein you can see the presence of the parent chain as aniline, we can see radicals at the nitrogen, named by N-ethyl and N-methyl which are the present alkyl substituents. In such a way, the benzene ring is not considered an alkyl radical because it belongs to the parent chain on aniline and therefore, N-ethyl-N-methylaniline has two alkyl substituents.
Best regards!
Answer:
Percent error = - 8.1 %
Explanation:
Given data:
Actual mass = 27.20 g
Theoretical mass = 25.01 g
Percent error = ?
Solution:
Formula:
Percent error = theoretical value- actual value/ actual value × 100
Now we will put the values in formula.
Percent error = 25.01 - 27.2 / 27.2 × 100
Percent error = -2.19 / 27.2 × 100
Percent error = -0.081 × 100
Percent error = - 8.1 %
