The number of significant figures in 0 .025 has to be given. Concept Introduction: Significant figures: The digits that are measured in a number including one estimated digit are called as significant figures. All nonzero digits are always significant. Exact numbers are always significant. Rules for determining when a zero is a significant figure: Rule 1: A zero is considered as a significant figure when it is seen between two nonzero digits and at the end of a number with a decimal point. Rule 2 A zero is not considered as a significant figure when it is seen at the beginning of a number and the end of a number, which does not contain a decimal point.
