What is the number of significant figures in 0.0001230?
Step 1: Identify the non-zero digits in the number. In 0.0001230, the non-zero digits are 1, 2, and 3.
Step 2: Count the non-zero digits. There are 3 non-zero digits: 1, 2, and 3.
Step 3: Look for any zeros that come after the last non-zero digit. In this case, there is a zero after 3.
Step 4: Remember that trailing zeros (zeros after a non-zero digit) in a decimal number are significant. So, the zero after 3 counts.
Step 5: Add the trailing zero to the count of significant figures. Now we have 1, 2, 3, and the trailing zero, making a total of 4 significant figures.
