The following prompt will be used to answer the first six questions. An experiment was performed to separate the components of a binary mixture composed of sucrose (sugar) and sand. The following data was collected in lab during the experiment. Mass of original binary mixture: 20.100 ± 0.001 g Mass of initial filter paper: 21.206 ± 0.001 g Mass of filter paper and isolated sand: 25.226 ± 0.001 g q1 Given the data and information in the prompt, what percent of sand is in the original mixture with absolute error? You will submit your answer in three parts. For this question, what value do you get for the percent of sand? You only need to submit the value here since the sig figs and error will be entered in the next two questions. You do not need to include the % symbol with your answer.
