CHEMISTRY 11 – EXPERIMENTAL UNCERTAINTY OF APPARATUS WORKSHEET. (1) Record the values for the experimental uncertainty encountered in using the following apparatus: Apparatus. Difference between numbered divisions. # of unnumbered subdivisions between numbered divisions. Smallest unnumbered divisions.
The uncertainty in a measurement can be expressed in two useful ways: a. as the absolute uncertainty in the last digit written b. as the percent uncertainty calculated as follows
17 cze 2023 · If you look at a 10 mL graduated cylinder, for example, the smallest graduation is tenth of a milliliter (0.1 mL). That means when you read the volume, you can estimate to the hundredths place (0.01 mL). You must use the bottom of the meniscus to determine the volume in the 10 mL graduated cylinder.
Use the following scales to measure the quantities required. Be sure to list the appropriate number of digits, as well as the uncertainty that goes along with each measurement. GRADUATED CYLINDER (mL): BEAKER (mL): BURET(mL): V = ______________. V = ______________. BALANCE (g): V = ______________.
Use the 10 mL graduated cylinder, which will be accurate to two significant figures. Mathematical operations are carried out using all the digits given and then rounding the final result to the correct number of significant figures to obtain a reasonable answer.
3) Calculate the % intrinsic error when a 10 mL graduated cylinder is used to measure the following volumes: a) 1 mL: b) 2.5 mL: c) 5.0 mL: d) 10.0 mL: Which is the most practical volume to measure with a 10 mL graduated cylinder? 4) Calculate the % intrinsic error when 0.5 mL of liquid is measured using the following: a) 10 mL graduated cylinder:
