(a)
Interpretation
The uncertainty in the final answers of the given mathematical operations and the number of significant figures in the final answers has to be found.
Concept introduction:
The measurement of specified components is one of the important stage in any laboratory analysis. Any error occurring in a measurement process can affect the accuracy of the result. Uncertainty is the range of values that is possible for a particular calculation. For example the measurement of length of a substance was reported to have the following values,
Significant figures are the numbers, which is contributing a particular value or meaning to the measurement. For example the number of significant figures in 0.12 is two.
