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 55.0 ml and the mass is 49.0 grams. Show all your working and explanation.

What is the density of the oil, with uncertainty?
