2. If Student A measures the volume of a liquid and reports its volume as 23.50 mL
and Student B measures a different amount of the same liquid and reports its
volume as 15.0 mL, is it likely that the students used the same measuring device?
Yes or no? Explain your answer.
3. If you were asked to measure 25.0 mL of a liquid and to transfer it to another
container, which of the following glassware could you use? Choose all that apply.
Give reason(s).
a) A 50-mL buret with smallest divisions of 0.1 mL
b) A 50 mL beaker with smallest divisions of 10 mL
c) A 50-mL volumetric flask
d) A 50-mL graduated cylinder with smallest divisions of 1 mL
e) A 25-mL pipet
4. A group of five students attempted to estimate 100 g of a substance by balancing
the amount of the substance with a 100-g standard mass and obtained the following
masses after each estimated amount was weighed: 95.8634 g, 80.8125 g, 106.5078
98.2865
and 86.4453
Create a data table as shown below and use the data
g,
to determine the answers to the following questions:
Mass (g)
g,
g.
Deviation (g)
% Deviation
Error (g)
% Error
a) What is the mean? And what is the true value?
b) What are the deviation and % deviation from the mean for each value?
c) What are the error and % error for each value?
