Chapter 1, Problem 26PE
When non-metric units were used in the United Kingdom, a unit of mass called the pound-mass (lbm) was employed, where 1 lbm = 0.4539 kg. (a) If there is an uncertainty of 0.0001 kg in the pound-mass unit, what is its percent uncertainty? (b) Based on that percent uncertainty, what mass in pound-mass has an uncertainty of 1 kg when converted to kilograms?

The mass of a block of wood is (3.15 ± 0.05) kg and its volume is (6.35 ± 0.02) x 103 cm3. Using the relationship: density = mass/volume, solve for density and find the uncertainty in density of wood in kg/m3 units.
