Answer:
14.8 g/mol
Explanation:
Starting on the left, count in 3 numbers (14.8), then round using the next number (0.02).
Because 2 is less than 5, the number stays the same and is not rounded up.
Answer:
96.3%
Explanation:
Data obtained from the question include:
Theoretical yield = 54g
Actual yield = 52g
Percentage yield =..?
The percentage yield can be obtain as follow:
Percentage yield = Actual yield /Theoretical yield x 100
Percentage yield = 52/54 x 100
Percentage yield = 96.3%
Therefore, the percentage yield of the reaction is 96.3%
