Concept explainers
Interpretation:
The significant figures in the measurement 0.0330 have to be selected from the given list.
Concept Introduction:
Significant figures are the digits that are present in a measurement which is known with certainty plus one digit that is estimated. Whenever a measurement is made, the significant figures in the measured quantity give the actual measurement. For this the significant figures should be recognized first. The significant figures may be non-zero digit and zero digit. But Zero may be or may not be a significant figure. It depends on where the zero appears. Leading zeros in the front of any number are never significant. Zeros between the numbers are significant. Zeros appearing at the last (trailing zeros) are significant if a decimal point is there in the number.
