Three students are asked to determine the mass of a coin. They each measure different values for the mass of the coin using a balance. Student A recorded a mass of 63.08g, student B recorded a mass of 63.022g and student C recorded a mass of 63.0328g. If the balance is sensitive go +-0.0001g which student recorded the mass correctly? Why?

Would it be student C? I'm not sure what to say for why though.

Anyone?
Answered by Michael Stone
i Would say c because the correct use of the significant figures. if the students only wrote down what student A or B got it would not be a "full" measurement.
