How do you compute a percent error?
% error = |experimental value - theoretical value|/theoretical value * 100% It is the absolute value of the differe nce betwee n the experime ntal a nd theoretical values divided by the theoretical value multiplied by 100%.
How weighing by difference eliminates systematic balance error in analysis of an unknown acetic acid solution experime?
Weighing by difference can reduce, but not eliminate, systemic errors in an experiment because systemic errors do not arise simply from errors in measurement, but from a variety of sources. Weighing by differences is still advised whenever possible.
Describe an experiment which can be used to investigate the effect of gamma radiation on mongo seeds include a description of how the dose can be varied and how you can set up controls in the experime?
An experiment which can be used to investigate the effect of gamma radiation on Mongo seeds can be described as follows; plant 5 seeds in different containers. Expose 4 seeds to different levels of gamma radiation. Document the growth levels of each seed, and the resulting plant or flower that is or is not produced.
