Which of the following is the largest volume?
4.5 x 102 m3
4.5 x 107 cm3
4.5 x 104 dm3
5.0 x 108 mm3

if you convert all of the following metrics to m^3. Then the first one is the largest number. I know this stuff did it last year

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
