Identify the digits in the measurement 0.0034 kg. The digits are '3' and '4', while the zeros before them are leading zeros.
Recall that leading zeros (zeros before the first nonzero digit) are not significant; they only indicate the position of the decimal point.
Count only the nonzero digits and any zeros between them or after them if applicable. Here, '3' and '4' are nonzero digits.
