Questions & Step-by-Step Solutions
In the number 0.0004560, how many significant figures are present?
Step 1: Identify the number given, which is 0.0004560.
Step 2: Understand that leading zeros (the zeros before the first non-zero digit) are not significant. In this case, the zeros before 4 are leading zeros.
Step 3: Count the non-zero digits. The digits 4, 5, and 6 are non-zero and are significant.
Step 4: Check for any trailing zeros (zeros after the last non-zero digit). The zero at the end of 4560 is a trailing zero and is significant.
Step 5: Add the significant figures together. You have 3 significant figures from 4, 5, and 6, plus 1 from the trailing zero, making a total of 4 significant figures.
