Question details

         You have a volume of oil that you weigh on an electronic balance. The smallest scale on the balance is 0.1 grams, and the manufacturer’s specifications indicate that the “accuracy” of the balance is “1% reading + 2 digits”. A 100 ml measuring cylinder is used to measure the volume of the oil. The measuring cylinder has a scale divided into 1 ml ranges, and the manufacturer has written “Tolerance = ± 1ml”. The volume measured is 40.0 ml and the mass is 38.5 grams.

(a)    What is the uncertainty and relative uncertainty in the mass of the oil? 

(b)  What is the uncertainty and relative uncertainty in the volume of the oil?

(c)  What is the density of the oil, with uncertainty
