How many significant digit are in 0.1020?
Significant digits are digits that provide useful information, for instance 123 has 3 significant digits and 30010 has 4 significant digits. So basically zeros aren't sign…ificant unless they are between two other numbers. 0.1020 has only 4 significant digits. A+: 4
4 significant digits.
There are four significant figures in 1.004.
Eight - all nonzero integers are significant.
Two. The decimal indicates that the zero is significant otherwise it wouldn't be a significant digit.
3. Any number that is not a 0 is a significant number. Rules for Significant Figures: 1. Non-zero numbers are always significant. (example: 1-9) 2. Zeroes between non-zeroes… are always significant. (ex: the zero in 908 is significant) 3. All final zeroes to the far right of the decimal place are significant. (ex: the zeroes in 34.0 and 7.0 is significant) 4. Zeroes that act as place holders are not significant. (ex: the zeroes in 600 are not significant) 5. Zeroes before a decimal act as place holders and are not significant. (ex. the zero in 0.12 is not significant)
One. The zeros are placeholders.
0.1020 is a number to 4 significant figures. The rule is that "Zeros must be kept to show the position of the decimal point or to indicate that zero is a significant figure." …Then the leading zero before the decimal point is retained as this shows the position of the decimal point. The zero between 1 and 2 is a key part of the number. The final zero (after 2) is a significant figure otherwise the number would be written 0.102. Consequently, the 4 significant figures are "1020" but are presented as 0.1020 to ensure the true value of the number is accurately given.
