Questions & Step-by-Step Solutions
Which of the following has 4 significant figures?
Step 1: Understand what significant figures are. Significant figures are the digits in a number that contribute to its accuracy.
Step 2: Identify the rules for counting significant figures. Non-zero digits are always significant. Any zeros between significant digits are significant. Leading zeros (zeros before the first non-zero digit) are not significant. Trailing zeros (zeros after a decimal point) are significant.
Step 3: Look at the number 25.00. It has two non-zero digits (2 and 5) and two trailing zeros after the decimal point.
Step 4: Count the significant figures in 25.00. The digits 2, 5, and the two trailing zeros count as significant figures.
Step 5: Conclude that 25.00 has a total of 4 significant figures.
