For example, if an instrument can measure up to 0.0001 kg, then a reading of 0.000236 kg implies that the measurement is accurate to the thousandths place, and the number of significant figures indicates the level of certainty in the measurement.<\/p>\n\n\n\n<p>In contrast, if the number had been written as <strong>0.00002360 kg<\/strong>, it would have four significant figures. This is because the trailing zero after the 6 is significant, as it is part of the decimal portion of the number. If the same number were written as <strong>0.0000236 kg<\/strong>, it would only have three significant figures, as there would be no trailing zero.<\/p>\n\n\n\n<p>Understanding significant figures helps maintain accuracy in scientific calculations and ensures that results are reported with the appropriate level of precision.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>0.000236 kg has_ significant figures. a 5 b 2 c 3 d 4 The correct answer and explanation is: The correct answer is C) 3.
