The general rule is that the final result should not be more accurate than the numbers used to obtain this final result. In the case of a multiplication or division, this means that the final result can't have more significant digits than the original numbers. One of the numbers has 4 significant figures, the other 3; therefore, the final result should be rounded to 3 significant figures. If more significant figures are quoted, a special note should be made that the last digits are uncertain.

How many significant figures are in the measurement cm?
None. The abbreviation cm represents one or more centimeters. In your question there are no numbers associated with the cm unit, therefore there are no significant figures.
How many significant figures are in 1.0054?
4 significant figures.
How many significant figures in 9400?
There are 3 significant figures in 94.2.
Why is the density expressed in two significant figures?
It is not always expressed in 2 sig figs. The number of sig figs depends on the accuracy of your measurements of mass and volume to calculate the density as well as any variables that you are expected to use the density with. There is no point in having a density expressed to 15 significant figures if then you are going to multiply it by volume expressed to 1 sig fig to determine the mass.
What is the umber of significant figures in 700.0?
Trailing zeros ALWAYS count as significant figures, so 700.0 would have 4 significant figures.
How many centimeters are there in a length 893.7 to three significant figures?
893.7cm to three significant figures is 894cm
How many centimeters are in 62.1 meters?
6210 centimeters this has 3 significant figures
Why is density expressed in two significant figures?
Because density expressed in two significant figures depends on your accuracy of your measurements of mass and volume to calculate as well as any variables that you are expected to use.
What is 1.3 gallons in cubic centimeters using 2 significant figures?
4900
What is the mass of 136 mL of Mercury?
If you know the density of mercury, you can determine the mass of a specific volume of mercury. Mercury has a density of 13.534g/cm3. 1cm3 = 1mL, so we can restate its density as 13.534g/mL. Density = mass/volume. If we know any two variables, we can manipulate the density equation to find the third variable. In this case, we know volume and density, so to find the mass, do the following calculation: Mass = density x volume Mass Hg = 13.534g/mL x 136mL = 1.84g Hg* *The answer is limited to 3 significant figures, because 136mL has only 3 significant figures, even though the density has 5 significant figures. When multiplying or dividing, the answer is limited to the same number of significant figures as the measurement with the fewest significant figures used in the calculation.
How many significant figures are in the measurement cm?
None. The abbreviation cm represents one or more centimeters. In your question there are no numbers associated with the cm unit, therefore there are no significant figures.
How many significant figures does the number of centimeters in exactly one meter have?
One. 1m = 100cm, and 100 has one significant figure.
What is the density of a regular soild if it weight 27 grams and has a volume of 95 cubi centimeters?
Density is found by dividing mass by volume. So in this case density = 27gm divided by 95cc = 0.2842 gm/correct to 4 significant figures) That means that each cubic centimetre of the solid has a mass of 0.2842 grams
What is the density of a rock that has a mass of 22.4g and a volume of 8cm3?
Density = mass/volume Density = 22.4g/8cm3 = 2.8g/cm3 or 3g/cm3 if significant figures are considered.
How many significant figures are in 1.0054?
4 significant figures.
How many significant figures in 9400?
There are 3 significant figures in 94.2.
How many significant figures 0.03?
There are 4 significant figures in 0.0032. Seems to be only 2 significant figures in this number.
