Questions & Step-by-Step Solutions

If a weight is recorded as 0.050 kg, how many significant figures does this weight have?
  • Step 1: Identify the number given, which is 0.050 kg.
  • Step 2: Look at the leading zeros before the first non-zero digit. In this case, the leading zeros are '0.'
  • Step 3: Understand that leading zeros (the zeros before the first non-zero digit) are not counted as significant figures.
  • Step 4: Identify the non-zero digits in the number. Here, the non-zero digits are '5' and '0' (the '0' after '5' is significant because it comes after a non-zero digit).
  • Step 5: Count the significant figures. The significant figures in 0.050 kg are '5' and '0', which gives us a total of 2 significant figures.
  • Significant Figures – Significant figures are the digits in a number that contribute to its precision, including all non-zero digits, any zeros between significant digits, and trailing zeros in the decimal portion.
