A method of expressing the accuracy of measured quantities is?
significant figures.
Ratio that compares 2 quantities measured in different units?
ratio that compares 2 quantities measured in diiferent units
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.
When adding or subtracting measured quantities what determines the number of decimal places?
I presume this is a question about scientific arithmetic. When adding or subtracting two numbers, with a different number of decimal places, the quantity with the least number of decimal places determines the number of decimal places in the answer. For example, let's say you are adding two masses: .1 grams .11 grams .1grams + .11grams = .21 grams Because .1 only has one decimal place, the answer becomes .2 grams, and we ignore the .01 because it is lost due to a lack of precision. The process of multiplying and dividing is different, as you compare significant digits instead of decimal places instead.
How many significant figures are in 20.60L measured quantity?
4
Are exact quantities considered when applying significant figure rules?
No, exact quantities are not considered when applying significant figure rules. Exact quantities are known with complete certainty and do not impact the uncertainty associated with measured quantities. Significant figures are only counted based on measured values.

significant figures.
What is the significant figures of this measured quantities 12.5 cm?
All three of them are significant figures
How many significant does 0.00000006 have?
"Dose" is a measured portion of a medicine. I am not aware of any number - no matter how small, that has measured quantities of medication - wther or not that dose is significant!
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 percent error in the measurement of the density of a substance, rounded to the appropriate number of significant figures?
The percent error in the measurement of density is calculated by taking the absolute difference between the measured value and the accepted value, dividing it by the accepted value, and then multiplying by 100. The result is rounded to the appropriate number of significant figures.
Which two physical quantities must be measured in order to determine the density of a liquid?
To determine the density of a liquid, two physical quantities that must be measured are the mass of the liquid and the volume of the liquid. Density is calculated by dividing the mass of the liquid by its volume.

Milk is measured in what quantities?
Milk is a liquid. liquids are measured in liters.
What is a quantity that can be measured?
A quantity that can be measured is length, which describes how long or short an object is. It can be measured in units like inches, centimeters, meters, etc.
How is bill of quantities measured?
A Bill of Quantities is measured using standard units of measurement such as area (sqm), length (m), volume (m³), or number (no.). Quantities are typically measured according to industry standards and specifications to ensure consistency and accuracy in estimating the costs of construction projects.
