1.	How many significant figures does 0.057 have?(a) 2(b) 4(c) 3(d) 0I had been asked this question during an interview.I want to ask this question from Uncertainty in Measurement in section Chemistry Basic Concepts of Chemistry – Class 11
Answer» Right answer is (a) 2 To explain I would SAY: The non-zero digits and any zeros between them are all SIGNIFICANT. Leading zeros are not significant. COUNTING all the significant digits GIVES us 2.
