Question

how many significant figures are in this number? 6.0

Explanation:

Step1: Recall sig fig rules

Significant figures: non - zero digits are significant, zeros between non - zero digits are significant, and trailing zeros in a decimal number are significant.

Step2: Analyze 6.0

The digit 6 is a non - zero digit (significant). The zero after the decimal is a trailing zero in a decimal number, so it is also significant. So we count 6 and 0.
