The initial quantities in the ideal gas are: \(p_1=1.12 atm\), \(V_1-33.5 L\), and \(T_1-108A0 C\). If you doubled the pressure and decreased the volume to half while changing its temperature to \(T_2=149^0 C\), how many moles of gas did you add or remove? Provide a positive value if you think gas was added, and a negative value if gas was removed.

Using a numerical integration method such as Simpson's rule, find the fraction of molecules in a sample of oxygen gas at a temperature of 250 K that have speeds between 100 m/s and 150 m/s. The molar mass of oxygen (O2) is 32.0 g/mol. A precision to two significant digits is enough.
One process for decaffeinating coffee uses carbon dioxide ( M=44.0 g/mol) at a molar density of about 14,0 mol/m3 and a temperature of about 60 . (a) Is CO2 a solid, liquid, gas, or supercritical fluid under those conditions? (b) The van der Waals constants for carbon dioxide are a=0.3658 Pa m6/mol2 and b=4.286105 m3/mol.
