In order to determine the density of a certain metal alloy in a
laboratory class a student is measuring the mass and the dimensions
of a cylinder made out of this alloy. She finds the mass to be
111.0 g with an uncertainty of 0.5 g. She then measures the
diameter and the height of the cylinder. The diameter is 59.0 mm,
and the height is 17.0 mm. The student made these length
measurements with a millimeter ruler.
What is the density of the alloy?
What is the relative uncertainty of this measurement in percent units? (Enter only a number without the percent sign.)
What is the absolute uncertainty of this density measurement?
Homework Answers
this problem is based on
propagation of error in products and divisions..standard results of
relative error in multiplication and division needs to be
remembered..
