I am helping my daughter do her chemistry homework and am stumped by this one. I have a beaker that seems to count by 50s.
That makes uncertainty calculations awkward. What is the “next unit down”?
How should one calculate uncertainty for this?
A real beaker says "approximate volume".
So the volume is approximately between 100 mL and 150 mL. So maybe 125 mL with an uncertainty of 25 mL. Your daughter would know best because she could apply exactly the rules she learned in class.
There is no universally accepted answer because the beaker is not made to measure volume accurately.
