Interpretation
The uncertainty in the final answers of the given mathematical operations and the number of significant figures in the final answers has to be found.
Concept introduction:
The measurement of specified components is one of the important stage in any laboratory analysis. Any error occurring in a measurement process can affect the accuracy of the result. Uncertainty is the range of values that is possible for a particular calculation. For example the measurement of length of a substance was reported to have the following values,
Significant figures are the numbers, which is contributing a particular value or meaning to the measurement. For example the number of significant figures in 0.12 is two.

- The density of an irregularly shaped object was determined as follows. The mass of the object was found to be 28.90 g 0.03 g. A graduated cylinder was partially filled with water. The reading of the level of the water was 6.4 cm3 0.1 cm3. The object was dropped in the cylinder, and the level of the water rose to 9.8 cm3 0.1 cm3. What is the density of the object with appropriate error limits? (See Appendix 1.5.)arrow_forwardAccording to the Official Rules of Baseball, a baseball must have a circumference not more than 9.25 in or less than 9.00 in and a mass not more than 5.25 oz or less than 5.00 oz. What range of densities can a baseball be expected to have?

- A measurement of the mass of a specimen was determined to be 4.203 plus or minus 0.001 g. What is the fractional uncertainty in the mass?arrow_forwardI am told that when determining the number of significant figures, if the decimal place is absent, then you start counting from the first nonzero number on the right side and continue counting to the left until you reach the last digit. However, if the decimal place is present, start counting the first nonzero number from the left and continue counting to the right until the final digit has been reached. For example, the number 50 only has two significant figures, while the number 50.00 has four significant figures. However, how does the number 50 have two significant figures? If I have to start countingfrom the right because of the absence of a decimal place, and I have to begin with the first non zero number, I would have to start from 5 and there is nowhere to count further to the left. How does the number 50 have two significant figures?arrow_forwardI did the calculation and I found 3.34 and would it be wrong if I put this as my answerarrow_forward
