How does conversion factors affect the number of significant figures in a problem?

If the conversion factor is exact, then the number of significant figures in the answer is the same as the number of significant figures in the original number.If the conversion factor is an approximation, then the number of significant figures in the result is the lesser of this number and the number of significant figures in the original number.


What number do you get when rounding the number 000721004 to three significant figures?

721000 is the result.


Rules in determining significant figures in four fundamental operations?

The simple rule is: no more significant figures than the least accurate of the values in the computation. For multiplication and division, the result should have as many significant figures as the measured number with the smallest number of significant figures. For addition and subtraction, the result should have as many decimal places as the measured number with the smallest number of decimal places. (Rounding off can be tricky, but that would be another thread)


In adding the measurements 11.074 m 18.2 m and 16.943 m what should be the number of significant figures in the result?

Three significant figures: two before the decimal point and one after.


When numbers are divided or multiplied the calculated result is rounded off to the same number or significant figures present in the factor with the least number of significant figures?

Yes. That's a step you should usually include, to avoid the result from looking more accurate than it actually is.

In adding the measurements 11.074m 18.2m and 16.943m what should be the number of significant figures in the result?

The least number of significant figures in any number of the problem determines the number of significant figures in the answer.


When multiplying and diving measured quantities the number of significant figures in the result should be equal to the number of significant figures in?

the measured quantity with the least number of significant figures. For example, if you multiply a quantity with 3 significant figures by a quantity with 2 significant figures, your result should have 2 significant figures.


What is the significant figures 4.884 x 2.25?

4.884 has four significant figures and 2.25 has three significant figures. 4.884 x 2.25 = 10.989 = 11.0 rounded to three significant figures. When multiplying or dividing, the result must have the same number of significant figures as the number in the problem with the fewest significant figures.


What number do you get when rounding the number 000721004 to three significant figures?

721000 is the result.


When you add or subtract what is the rule for determining the number of significant figures in the answer?

When adding or subtracting numbers, the result should have the same number of decimal places as the least number of decimal places in the original numbers. This is because in these operations, you are limited by the least precise measurement. Significance figures don't matter in addition or subtraction, only decimal places.


What appropriate number of significant figures to be used in expressing the result of 51.6x3.1416 is?

The appropriate number of significant figures to use in expressing the result of 51.6 x 3.1416 is three. This is because the factors each have three significant figures, so the result should also have three significant figures. The answer would be 162.
