Title: Degree of Uncertainty for Volume Measurement of a Liquid in a Graduated Cylinder
Post by: lexxxlouu on August 24, 2006, 10:54:38 PM

i need to know how to read various graduated cylinders. i can't really explain, but, like how many digits need to follow the decimal for certain cylinders including the uncertain digit. for example when can i just write 56.0 mL & when do i write 4.35 mL???

please help me out or give me a website that will give me this info!!
thank you.

check the particular measuring cylinder; if the smallest division corresponds to 0.1, then use 1 decimal point. if 0.2, then 1 decimal point. if 0.05, then 2 decimal points.

pretty much common sense, so u won't need a website for this. good lucky with your test (although its pretty late since this reply, :P)
