At room temperature the element bromine, \(\mathrm{Br}_{2},\) is a liquid with a density of 3.12 \(\mathrm{g} / \mathrm{cm}^{3} .\) Calculate the mass of 125 \(\mathrm{mL}\) of bromine. What volume does 85.0 \(\mathrm{g}\) of bromine occupy?
What data would you need to estimate the money you would spend on gasoline to drive your car from New York to Chicago? Provide estimates of values and a sample calculation.
At the Amundsen-Scott South Pole base station in Antarctica, when the temperature is \(-100.0^{\circ} \mathrm{F}\) , researchers who live there can join the 4300 \(\mathrm{Club}^{\prime \prime}\) by stepping into a sauna heated to \(200.0^{\circ} \mathrm{F}\) then quickly running outside and around the pole that marks the South Pole. What are these temperatures in $^{\circ} \mathrm{C} ?\( What are these temperatures in \)\mathrm{K}$ ? If you measured the temperatures only in \(^{\circ} \mathrm{C}\) and \(\mathrm{K}\) , can you become a member of the \(" 300 \mathrm{Club}^{\prime \prime}\) (that is, is there a 300 .-degree difference between the temperature extremes when measured in \(^{\circ} \mathrm{C}\) and \(\mathrm{K}\) )?
