Student A has collected data for the mass of a sample of gold (Au) over five trials. The accepted mass of the Au is 25.56 g. After massing the Au on the scale, Student A recorded the following measurements:
Scale Number | Mass of Au in Grams
1 | 22.53
2 | 22.51
3 | 22.56
4 | 22.54
5 | 22.59

Comment on the accuracy and precision of this data set. Explain your reasoning.

Measurement is a concept we take for granted in our daily doings. However, it is a very important part of not only chemistry as a science, but our everyday lives. With that said, explain how measurement and its vocabulary are applied in your day to day living. Why are measurements and the process of measuring relevant to humankind

The Universe is surely a vast, infinite place with an infinite number of forms of matter. The Universe is the house for all that is large and unseen (except with the aid of a telescope) as well as small and unseen (except with the aid of a microscope). With that said, please collect data on three objects found in the universe. For example, you can describe a certain planet, certain building, or certain animal; however, the object should be considered "extreme" in a large or small sense. (An example that you cannot use specifically would be Mount Everest - which is known for its extreme height.) In a blog post, please post the name of each object as well as the reported measurements of the objects. Also, include the link or source of the reported measurements.

Hi. I am doing the Lab right now, and I am stuck on one question. When we report the measured value of flask as "average +/- absolute error". They require the error rounded to one digit. My error is 0.006. I do not know how to round it to one digit. Can anyone help me?
