Answer:
The answer is 0.91 %
Step-by-step explanation:
The percentage error of a certain measurement can be found by using the formula
![P(\%) = (error)/(actual \: \: number) * 100\% \\](https://img.qammunity.org/2021/formulas/chemistry/high-school/q0zosffwg85xn9jdfzfbo353sezuv4qp22.png)
From the question
actual volume = 198.2 mL
error = 200 - 198.2 = 1.8
So we have
![P(\%) = (1.8)/(198.2) * 100 \\ = 0.90817356205...](https://img.qammunity.org/2021/formulas/chemistry/high-school/qqrkiyn5xe854aheqz3e2sdd1otfhg8ega.png)
We have the final answer as
