(a) Interpretation: The weight of an average potato using the correct number of significant figures is to be calculated. Concept introduction: Scientific notation is used to write large numbers by shifting the decimal point. It is expressed as the product of a decimal term and 10 raised to some power. Significant figures are used to express a measurement in scientific notation. The significant figures reflect the closeness of measured values to the standard values.
