How many significant figures in 4.023?
There are 4 significant figures. If a number has a decimal point with some zeroes, we count the total number of digits. Therefore, we count four significant figures.
How many uncertain digits are present when some quantity is expressed in significant figures?
one
Is 0.2 the same as 0.200?
Yes, 0.2 is the same as 0.200. When a number is written with trailing zeros after the decimal point, it does not change the value of the number. Both 0.2 and 0.200 represent the same quantity, which is two tenths.
What are some square numbers and the answer is five?
25's square root is 5
List some rules used to determine the number of significant figures and how they differ for addition and subtraction vs multiplication and division?
For multiplication/division, use the least number of significant figures (ie 6.24 * 2.0 = 12). For addition subtraction, use the least specific number (ie 28.24 - 2.1 = 26.1)
What is an example for significant figures?
Significant figures are important for science, they tell how certain you are of a certain value. The rules for significant figures are as follows: If it is a decimal number, look at the first number on the left. If it is not zero, start counting the amount of numbers, and that's how many significant figures you have. For example, 7.495 has 4 significant figures. If it is zero, keep going until there is digit larger than zero, and start counting the numbers until the end. However many numbers there are, that's how many significant figures you have. For example, 0.000331 has 3 significant figures. If the number does not have a decimal, start from the right and if the number is not zero, start counting numbers and that's how many significant figures you have. For example, 93847 has 5 significant figures. If it is zero, the first significant figure will be the first non-zero digit. For example 3873000 has 4 significant figures. When you add or subtract some numbers, the amount of significant figures the answer should be expressed in depends on the number with the least amount of decimal places. For example, 4.398 + 5.2 = 9.6 You express the answer to the lowest number of decimal places a value you are adding or subtracting has. When you multiply or divide numbers, the answer is expressed to the lowest amount of significant figures that the values have. For example: 55 x 7 = 400 (when expressed with correct significant figures)
How many significant figures in 8.00?
There are some rules for finding significant figures. here there is a problem how many significant figures in 8.00. here in 8.00 have three significant figures. Because after decimal point they may have zeros. but we have to take this as significant figures.

The number 221.5 contains how many figures?
Four significant figures. Review you rules for significant figures. Some chemistry teachers, especially at the college level, are very concerned with significant figures.
How many significant figures in 4.023?
There are 4 significant figures. If a number has a decimal point with some zeroes, we count the total number of digits. Therefore, we count four significant figures.
How many significant figures are in the number 120?
A significant figure is basically counting how many digits there are: In this case this number is to FOUR significant figures because there are FOUR digits. Here's some more examples: When you have zero's in front of the number, these do not count as digits: so, if you had 0.0034, you only count the 3 and 4 as digits so this would be to TWO significant figures. However, if you have 0.003404, you must count the zero in between the two four's because this is part of the number - there are FOUR significant figures here.

How many significant digits are in 2.56 14.0002?
All of the digits you've listed are significant. If we're supposed to perform some operation on them, the least number of significant figures in any number of the problem determines the number of significant figures in the answer.
Are all 5-sided figures similar?
No. There are some figures that don't have a name that are five sided.
How many significant digits are in the measurement 589.040 Newtons?
The answer is 3. Significant figures in a whole numbers are integers on the left of the decimal point beginning with the first non-zero number. That's confusing so let me use some examples: 589. has 3 because there are no zeros to the left of the decimal and 3 numbers 5089. has 4 because there are no ending zeros and 4 numbers. 5890. has 3 because only the the zero is next to the decimal. 58900. also has 3.
How do you change things in to significant figures?
The rules for identifying significant figures when writing or interpreting numbers are as follows: All non-zero digits are considered significant. For example, 91 has two significant figures (9 and 1), while 123.45 has five significant figures (1, 2, 3, 4 and 5). Zeros appearing anywhere between two non-zero digits are significant. Example: 101.1203 has seven significant figures: 1, 0, 1, 1, 2, 0 and 3. Leading zeros are not significant. For example, 0.00052 has two significant figures: 5 and 2. Trailing zeros in a number containing a decimal point are significant. For example, 12.2300 has six significant figures: 1, 2, 2, 3, 0 and 0. The number 0.000122300 still has only six significant figures (the zeros before the 1 are not significant). In addition, 120.00 has five significant figures since it has three trailing zeros.
How many uncertain digits are present when some quantity is expressed in significant figures?

The number 50.775 has how many significant figures?
5. Count all digits except trailing zeros. So 50.775 has 5 significant Figures. 50.775000 has 5 as does 507750000. Remeber only discount trailing zeros so 50.775001 has 8 sigificant figures.Right answer, wrong explanation :)According to Wikipedia, trailing zeros after the dp aresignificant. 50.775000 therefore has 8. The logic is that you could have written it as 50.775 so the fact you bothered to write it with the zeros means that it is accurate to 6 decimal places.Your 507750000 has 5 significant figures as you say but 507750000 with the tens digit emphasised in some way has 8. The logic is that the emphasis means the zero really is zero, so everything up to it is significant.507750000. has 9: the dp is numerically superfluous but means that all the digits before it are significant.00507750000 officially has 5 but there must be some reason it's been written with leading zeros so it may be taken to have 7. Typically this would be done to stop the number of sig figs from jumping around with different values."Significant figures" is a slightly woolly concept!
