How do you answer the correct number of significant figures?
Rules for Using Significant Figures
- For addition and subtraction, the answer should have the same number of decimal places as the term with the fewest decimal places.
- For multiplication and division, the answer should have the same number of significant figures as the term with the fewest number of significant figures.
How many significant figures are there in 0?
one significant figure
The number 0 has one significant figure. Therefore, any zeros after the decimal point are also significant. Example: 0.00 has three significant figures. Any numbers in scientific notation are considered significant.
How many significant figures does the number 2.4 have?
four significant figures
By rule 4, the first three zeros are not significant, but by rule 2 the zero between the sixes is; therefore, this number has four significant figures. By rule 2, the two zeros between the twos are significant, so this measurement has four significant figures.
Does 0.0 have any significant figures?
The number 0 has one significant figure. Therefore, any zeros after the decimal point are also significant. Example: 0.00 has three significant figures. Any numbers in scientific notation are considered significant.
When we add 0.9825 to 3.04 the correct result with regard to significant figures is?
When we add 0.9825 to 3.04, the correct result with regard to significant figure is (1 Point) 4.0225.
How many significant figures does 83.400 have?
How Many Significant Figures?
| Number | Scientific Notation | Significant Figures |
|---|---|---|
| 83.400 | 8.34×101 | 5 |
| 801.5 | 8.014×102 | 4 |
| 90 | 9.0×101 | 1 |
| 900 | 9.0×103 | 1 |
How many significant figures are there in 12340?
4 significant digits
Trailing zeroes in a number without a decimal point may or may not be significant. 12340 may have 4 significant digits or 5 significant digits. The only way to know for sure is to use scientific notation (1.2340 × 104 has 5 significant digits; 1.234 × 104 has 4 significant digits).
How many significant figures are there in the number 0.0 1010?
three significant figures
In the case of 1010, there are two non-zero digits, i.e., one and two zeros, one zero is sandwiched between two non-zero digits, and one zero is trailing zero. So only one zero will be considered as a significant figure. Hence, three significant figures are present in the number 1010.
What is a 3 significant figure?
The third significant figure of a number is the digit after the second significant figure. This is true even if the digit is zero, and so on. We round a number to three significant figures in the same way that we would round to three decimal places. We count from the first non-zero digit for three digits.
What is the rule for how many significant figures you are able to get using a measuring instrument quizlet?
The answer must have as many decimal places as the measurement having the least number of decimal places.
Which of the following rules regarding the significant figures and their calculation are not correct?
Which of the following rules regarding the significant figures and calculations involving them is not correct? Answer to a multiplication or division is rounded off to the same number of significant figures as possessed by the least precise term in the calculation.
