1. 4.78/5 points | Previous AnswersNCSUGenChem202LabV1 1.T.001. Significant Figures Tutorial Significant figures and decimal places play an important role in science because they are a proxy for measurement precision. Chemistry, being an experimental science driven largely by precise determinations of specific amounts, requires the use of precision in answering scientific questions. The rules WebAssign follows are generally accepted and may even be spelled out in your textbook. If you want...
