Most Accurate Device for Measurement
« on: December 11, 2014, 12:47:49 AM »
Found an interesting question from my Final today:

What is the most accurate device for measuring the volume of liquids?

A. Beaker
B. Erlenmeyer
C. Graduated Cylinder
D. Volumetric Pipette


It could not be A or B because these containers are only for relative measurements of volume, as I have been taught. I reasoned that it was C because graduated cylinders are designed for that purpose. Any thoughts?

Graduated cylinders are not that accurate.

Yeah, I thought so. C seemed the most logical at the moment, but now that I thought back about it I realize just how stupid my reasoning was.

Whelp, there goes my chemistry career. 89 in Gen Chem 1.

I got an 89 in my second semester of general chemistry and they haven't kicked me out of the program yet.
I don’t know why a teacher can’t spare just one percentage point though.
