Questions & Step-by-Step Solutions
If a measurement is recorded as 0.004560, how many significant figures does it have?
Step 1: Identify the number given, which is 0.004560.
Step 2: Look for leading zeros. Leading zeros are the zeros before the first non-zero digit. In this case, the leading zeros are the three zeros before the 4.
Step 3: Count the significant figures. The significant figures start from the first non-zero digit. Here, the significant figures are 4, 5, and 6.
Step 4: Include the trailing zero after the 6. Trailing zeros in a decimal number are significant. So, we count the 0 after the 6.
Step 5: Add up the significant figures: 4, 5, 6, and the trailing 0 gives us a total of 4 significant figures.
