you do not always have to put it there, but some teachers want you to. hope this helped.
No. Not unless there is another real (1-9) number to the left of the zero. If, or instance, your number is 0.45 only the 4 and 5 are significant. But, if you have 70.45 then the zero IS significant.

Does a zero after a decimal count as a significant figure?
no
How many significant digits are 0.1020?
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.
0.1709 to 1 significant figure?
0.1
How many significant figures are in the number 0.0003?
0.003 has one significant figure. A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant.
How do you round 0.00076321 into 3 significant?
Two rules associated with significant figure :-. When rounding off numbers is "If the first figure to be discarded is 5 or more then the previous figure is increased by 1". Zeros must be kept to show the position of the decimal point or to indicate that zero is a significant figure. Then 0.000 must be kept to show the position of the decimal point. 763 are thus the three significant figures and no change is required as the first figure to be discarded is 2 and this is less than 5. The answer to 3 significant figures is 0.000763
Does a zero after a decimal count as a significant figure?
no
What is significant figure of 0.0050?
0.0050 has two significant figures, the 5 and the trailing 0. The trailing zero is significant because it comes after the decimal. The leading zeroes before the 5 are place holders and are not significant.

How many significant figures are in 0.7?
0.7 has one significant figure. Any non-zero digit is significant (165 has three significant figures). Any zero between non-zero digits is significant (304 has three significant figures). Any zero to the right of a non-zero digit in a number which includes a decimal point is significant (10,000 has one significant figure, .0001 has one significant figure, but 100.0 has four significant figures, as does 0.001000). In this case, only the 7 is significant.
How many significant figure are in the measurement of 1.050?
four The one and five are automatically significant because they are non-zero digits. The first zero is significant because it is between two other significant figures, and the trailing zero is significant because it comes after a decimal point.
What is the 1st significant number in a decimal?
It is the first non-zero digit, starting from the left. It can be before or after the decimal point.
How many significant figures does 0.002300 have?
In this case, where there are no non-zero digits to the left of the decimal point, the number of significant figures is equal to the number of digits to the right of the decimal point from the rightmost figure to leftmost non-zero digit. In this case, there are four significant digits
What is the measurement of 417.32 g in significant figure?
The measurement of 417.32 g has five significant figures. Each non-zero digit and any zeros between them are considered significant in a decimal number.
How many significant figures does 0.50 have?
0.50 has two significant figures, the 5 and the trailing 0 after the decimal point. The leading zero before the decimal point is not significant.
How many significant digits are contained in the number 0.000540?
THREE Although they are an important part of the number the three zeros after the decimal point are positional zeros. The rule is :- " Zeros must be kept to show the position of the decimal point or to indicate that zero is a significant figure." The final zero (after 54) is the third significant figure. 0.000 540 **** positional zeros. 0.000 540 ..........*** significant figures (three)
How many significant digits are in this numbe 0.00909?
3. The first non zero number is the first significant figure. All numbers after this are significant. Trailing zeros after the decimal place have no value
