Answer:
[tex]e(\%)=0.17\%[/tex]
Explanation:
Volume of a drop:
[tex]V_{drop}=\frac{1 mL}{20 drop}[/tex]
[tex]V_{drop}=0.05 mL[/tex]
To estimate the error:
[tex]e(\%)=\frac{V_{real}-V{theorerical}}{V{theoretical}}*100\%[/tex]
[tex]e(\%)=\frac{(30 mL+0.05mL)-30mL}{30mL}*100\%[/tex]
[tex]e(\%)=0.17\%[/tex]
