Acontainer with volume 1.77 l is initially evacuated. then it is filled with 0.226 g of n2. assume that the pressure of the gas is low enough for the gas to obey the ideal-gas law to a high degree of accuracy. if the root-mean-square speed of the gas molecules is 178 m/s, what is the pressure of the gas?

The starship enterprise is caught in a time warp and spock is forced to use the primitive techniques of the 20th century to determine the specific heat capacity of an unknown mineral. the 125-g sample was heated to 96.3°c and placed into a calorimeter containing 85.9 g of water at 20.0°c. the heat capacity of the calorimeter was 14.2 j/k. the final temperature in the calorimeter was 24.5°c. what is the specific heat capacity (in j/g°c) of the mineral? enter to 4 decimal places.
