When the measured quantity 45.67 kg is divided by the measured quantity 3.42 L the answer should have how many significant figures?

When divided by a calculator 45.67kg/3.42L equals 13.35 kg/L. Of the two quantities the highest common certainty we have is the 3 significant figures from the volume. Therefore the answer would be 13.4 kg/L rounded to three places.

What is the correct answer for the calculation of a volume in mL with measured numbers 28.58 divided by 128.32?
When you multiply 16 x 8.02 it equals 128.32, which has 5 significant figures. When you divide 28.58 into 128.32 it gives you 0.223 mL and it needs to be rounded to four significant figures.
Why significant figures represent the precision of a measurement and not its accuracy.?
A measurement that has a larger number of significant figures has a greater reproducibility, or precision because it has a smaller source of error in the estimated digit. A value with a greater number of significant figures is not necessarily more accurate than a measured value with less significant figures, only more precise. For example, a measured value of 1.5422 m was obtained using a more precise measuring tool, while a value of 1.2 m was obtained using a less precise measuring tool. If the actual value of the measured object was 1.19 m, the measurement obtained from the less precise measuring tool would be more accurate.
How many significant figures are in 8630000.000?
It only has 3 significant figures, 863.
How many significant figure for 2.9979 x 108?
5 significant figures Each figure that contributes to the accuracy of a value is considered significant. So 2.9979 has 5 significant figures. The 10^8 does not contribute to the accuracy as it simply indicates the number of trailing zeroes (i.e. 299,790,000) that are simply a result of rounding from the actual value (299,792,458)
What is the importance of significant figures?
significant figures make data analysis less ambiguous and therefore much easier.. toindicatethe number of digits in a measurement

How is precision related to the significant figures in a measured quantity?
The greater the number of significant figures, the greater the precision. Each significant figure increases the precision by a factor of ten. For example pi = 3.14 is accurate to 3 significant figures, while pi = 3.14159 with 6 significant figures is a more accurate representation.
What are the rules in multiplication and division of significant figures?
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.
Why are significant figures used and how are significant figures obtained?
Significant figures are used to receive a more accurate number. To obtain the number you you multiply or divide the quantities, leave as many significant figures in the answer as there are in the quantity with the least number or significant figures. If adding or subtracting quantities, leave the same number of decimal places in the answer as there are in the quantity with the least number of decimal places
When multiplying and dividing measured quantities the number of significant figures in the result should be equal to the number of significant figures in what?
The number of significant figures should be equal to the significant figures in the least precise measurement.
