Your professor has recruited you to work in her lab to help her win the Nobel Prize. It is critical that your work be as accurate as possible. Rather than using the stated volumes of glassware in the lab, you decide to calibrate each piece. An empty 10-mL volumetric flask weighed 10.263 4 g. When filled to the mark with distilled water at 208C, it weighed 20.214 4 g. What is the true volume of the flask?

The unit of kiloton is used to describe the energy released during large explosions. It was originally defined as the explosive capability of 1000 tons of trinitrotoluene (TNT) high explosive. Because that expression can be imprecise depending on the explosive's exact chemical composition, the kiloton subsequently has been redefined as the equivalent of 4.186 x 1012 J. In the units of kiloton, calculate the kinetic energy of an asteroid that has the size (box-shaped, 13 x 13 x 25 km) and composition (density, 2.4 g/cm) of an asteroid. Kinetic energy is defined by U. = mv? where m is the object's mass and v is its speed. Objects passing through the inner solar system generally have speeds in the range of 20 km/s.
