Use the rules of significant figures to answer the following : 22.674 * 15.05. Answer: 341.2

The number 3400 has two significant figures. The rules for significant figures can be found by using the link to our friends at Wikipedia.

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.

Four significant figures. Review you rules for significant figures. Some chemistry teachers, especially at the college level, are very concerned with significant figures.

You count the number of figures from left to right starting with the first number different from 0. Example: 205 has 3 significant figures 0.0000205 has 3 significant figures 0.000020500000 has 8 significant figures

The rules in writing significant figures state that non zero numbers always significant. Zero numbers between the non zero numbers are also significant. Finally, if you write a number in scientific notation and you are able to get rid of the zeroes, they are not significant.

rules for calculating S.F. are: 1,all non zero digits r significant 2,

The least number of significant figures in any number of the problem determines the number of significant figures in the answer which in this case is 270.9

1. All non-zero digits are significant. For example, 295 has three significant figures. 2. Leading zeroes in front of a decimal are not significant. For example 0.295 has three significant figures. 3. Zeroes between other significant figures are significant. For example 2095 has four significant figures. 4. Trailing zeroes after a decimal are significant. For example 295.0 has four significant figures. And 2950 has three significant figures because the trailing zero does not occur after a decimal.

The least number of significant figures in any number of the problem determines the number of significant figures in the answer which in this case is 270.9

The least number of significant figures in any number of the problem determines the number of significant figures in the answer which in this case is 656.64

One of the rules of significant figures is that leading zeros are not significant; therefore, 0.00034 will only have TWO significant figures (3 and 4).

all non zero digits are significant .2.zeroes betweenother significant.

The accuracy of the answer is limited to the LEAST significant figures of the input. So if two measured quantities are multiplied or divided, one of which is accurate to only two significant figures, and other to six significant figures, the answer is only accurate to two significant figures. HOWEVER: use all the figures you have for the calculation, and then round your answer to two significant figures. Also, however, remember that if you are multiplying by an actual exact number, as in doubling, the significant figures of that 2 is unlimited, so the answer is only limited by the significant figures of the number you are doubling.

The least number of significant figures in any number of the problem determines the number of significant figures in the answer which in this case is 273.8

The least number of significant figures in any number of the problem determines the number of significant figures in the answer which in this case is 270.8

But according to the rules of significant figures, the least number of significant figures in any number of the problem determines the number of significant figures in the answer which, in this case, would be 11.

1. All non zero digit are significant. 2.

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.
