Answer: +/- 0.018
All you have to do is plug the known values into the equation and evaluate it.
First, do the work under the square root sign. 0.77(1-0.77) / 2100 gives you a very small number. If you take the square root of that, you will have 0.0091.
The last step is to just multiply that by 2 and you will have 0.018
1) subtract the accepted value from the experimental value.
2) Take the absolute value ofvstep 1
3) Divide the answer by accepted value
4) Maltiply that answer by 100 and add the % symbol to express the answer as a percentage.
Multiplication and division are opposites, or inverse operations
