please help answer the following questions in the picture above (percent error). thank you
I am not sure if you will need these other 3 pictures, but i will post them just in case!
(15pts) Percent Error At 25 C, the density of water is 0.997044 g/mL. Use this value to determine the percent error for the two density measurements (5pts) Calculate the percent error for density using graduated cylinder (5pts) Calculate the percent error for density using the burette readings, (5pts) What does the error tell you about the accuracy of the measurements. Choose the letter corresponding to the explanation that besta fits your results. A The graduated cylinder is a more accurate method to deliver volumes of liquid because it has a lower error B. The graduated cylinder is a more accurate method to deliver volumes of liquid because it has a higher error C. The buret is a more accurate method to deliver volumes of liquid because it has a lower error D. The buret is a more accurate method to deliver volumes of liquid because it has a higer error E. The buret and graduated cylinder ore equivalent methods to deliver volumes of liquid because because the error is the same Choose...
