Answer:
5.77% Error.
Explanation:
Given an experimental value of 275 g , and a theoretical value of 260 g, the percent error can be found using the equation:
[tex]\% \: error \: = \frac{ |theoretical \: value \: - \: experimental \: value | }{theoretical \: value} \times 100[/tex]
% Error = ( | 260 - 275 | / 260 ) × 100 = ( | - 15 | / 260 ) × 100 = ( 15 / 260 ) × 100 = 1500/260 = 300 / 52 = 5.769230769230.. ≈ 5.77%
