Calculate the kinetic energy (in eV) of a nonrelativistic neutron that has a de Broglie wavelength of 9.9  10-12 m. (h = 6.626  10-34 J  s, mneutron = 1.675  10-27 kg, 1 eV = 1.60 10-19 J)
 
  What will be an ideal response?

Question 2

How many moles of water (H2O) molecules are in a 4.00 m3 container at a pressure 8.00  105 N/m2 and temperature 600C? The ideal gas constant is R = 8.314 J/molK = 0.0821 L  atm/mol  K.
 
  A) 641 mol
  B) 7.72  1026 mol
