Final answer:
The solution within a 0.1% error tolerance level is determined by ensuring that the difference between the experimental value and the accepted value is less than or equal to 0.1% of the accepted value.
Step-by-step explanation:
The error tolerance level of 0.1 % means that the acceptable range for error is 0.1% of the measurement value. To find a solution within this tolerance, we need to ensure that the difference between the experimental value and the accepted value is less than or equal to 0.1% of the accepted value.
For example, if the accepted value is 100, the maximum acceptable error would be 0.1% * 100 = 0.1. So, any experimental value between 99.9 and 100.1 would be considered within the tolerance level of 0.1%.
