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
C) 2.65 1026 mol
D) 3.86 1026 mol
E) 441 mol
