Identify the digits in the number 64.00. The number consists of the digits 6, 4, 0, and 0.
Recall the rules for significant figures: all nonzero digits are significant, zeros between nonzero digits are significant, and trailing zeros in a decimal number are significant.
Since 64.00 has two trailing zeros after the decimal point, these zeros are significant because they indicate precision in the measurement.
Count all the digits: 6, 4, 0, and 0, which gives a total of 4 significant figures.
Therefore, the measured quantity 64.00 g has 4 significant figures.
