How do you find a significant figure?
Say 251.206 to 4 significant figures = 251.2 Say 251.274 to 4 significant figures = 251.3 Say 25461.214 to 2 significant figures = 25000
What is 2.072 to two significant figures?
To find a number to two significant figures or any amount of significant figures you look at one plus the amount of asked figures, in this case the third significant figure, and if it is 5 or greater increase the asked amount of significant figures by one. If it is 4 or less make no changes to your number. Finally report the calculated number with the asked amount of significant figures.
How many significant figures does 1.0070 have?
1.0070 has 5 significant figures. This is because when you are looking at a number with a decimal number, you start from the left and find a non-zero number. When you find the non-zero number, every number after it is significant.
How do you find two significant numbers?
significant figures are any numbers before or after a decimal point excep 0 so 01.2134 to 2 significant numbers is 1.2. if there is a 0 after a signifcant figure it counts for example.... 1.100 to three significant figures is 1.10
How do you find significant figures in calculation?
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 do you find the area of the figure of a rectangle?
Suppose you are asked to find the area of a rectangle that is 2.1- wide by 5.6- long. Your calculator answer would be 11.76 . Now suppose you are asked to enter the answer to two significant figures.
How many significant figures are in 0.00200?
To assess how many significant figures a number has been given to, you first need to find the greatest non-zero digit. In this case that is the 2. The next step is to count how many digits have been given after this one. In this case there are no more. Thus the figure 0.002 is to 1 significant figure.
How to find the upper and lower bound of 1000 to two significant figures (I know the ans is 950 and 1050 but I don’t know the steps )?
Lower and Upper bound of 1000 of two significant figures is 100Plus or minus 50 is 950 , 1050
What is the number of moles and the number of atoms in 2.30 grams of sodium?
From the periodic table, 1 mole of sodium is 22.989770g. To find the number of moles in 2.30g, multiply the known mass x (1mol/22.989770g). 2.30g Na X (1mol Na/22.989770g Na) = 0.100mol Na* * The answer is in 3 significant figures because 2.30g has 3 significant figures. When you multiply or divide, the answer is rounded to the same number of significant figures as are found in the number with the fewest significant figures.
How many significant figures are in 74.30?
Answer: four. All written decimals are significant (even if it is 0).However if you have a physics computation where one number turns out to be x = 2.0 (2 significant figures) and the other turns out to be y = 37.15 (4 significant figures), then to compute the product x*y you should take the least of these significant numbers you are using. Hence, you will find thatx*y = 2.0 * 37.15 (= 74.30) = 74 (rounded to the nearest number with 2 significant digits only.)So, it depends on the context you are using this number in.
How many significant figures are in 0.571429?
6. If the number has a decimal, starting from the left and moving to the right find the first nonzero digit. From there, count every single digit you come across (even other zeros). The number of digits you count is the number of significant figures.
