Significant Figure.
What are the number of significant figures in the measured value 0.320 g?
0.320g has three significant figures. A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant.
Each value measured in nature has a number value called its magnitude and a dimension or?
unit
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.
What is the value of the figure 7 in the number 5768?

What is the meaning of significant figure in business Maths?
Significant figures are the number of digits in a value, often a measurement, that contribute to the degree of accuracy of the value.
What is 150.932 to 1 significant figure?
When expressing a number to one significant figure, you round it to the nearest power of 10. In this case, 150.932 to 1 significant figure would be 200. Since 150.932 is closer to 200 than to 100, the rounded value is 200.
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
Give the use of significant figure?
It refers to the number of of some numerical value thet was obtained from an accepted level of accuracy
What is two significant figure of 151.208?
The number 151.208, when expressed to two significant figures, is 150. This is because the first two significant figures are '1' and '5', and rounding the next digit (which is '1') leads to a decrease in the last significant figure. Therefore, the rounded value is 150.
What is the percent error in the measurement of the density of a substance, rounded to the appropriate number of significant figures?
The percent error in the measurement of density is calculated by taking the absolute difference between the measured value and the accepted value, dividing it by the accepted value, and then multiplying by 100. The result is rounded to the appropriate number of significant figures.
How many significant figures are in 8.09?
There are three significant figures in the number 8.09. The first two digits, 8 and 0, are considered significant because they are non-zero numbers. The third digit, 9, is also significant because it follows a non-zero number and is a measured value.
measured value 28.7053cm which has six significant figures round the measurement to four significant figures?
28.71
Why significant figures represent the precision of a measurement and not its accuracy.?
A measurement that has a larger number of significant figures has a greater reproducibility, or precision because it has a smaller source of error in the estimated digit. A value with a greater number of significant figures is not necessarily more accurate than a measured value with less significant figures, only more precise. For example, a measured value of 1.5422 m was obtained using a more precise measuring tool, while a value of 1.2 m was obtained using a less precise measuring tool. If the actual value of the measured object was 1.19 m, the measurement obtained from the less precise measuring tool would be more accurate.
How many significant figure for 2.9979 x 108?
5 significant figures Each figure that contributes to the accuracy of a value is considered significant. So 2.9979 has 5 significant figures. The 10^8 does not contribute to the accuracy as it simply indicates the number of trailing zeroes (i.e. 299,790,000) that are simply a result of rounding from the actual value (299,792,458)
