COAST Tutorial Problem The solubility of air in water is approximately 2.1 x103 M at 20°C and 1.0 atm. Calculate the Henry's law constant for air Number mol/ L atm Is the KH value of air approximately equal to the sum of the KH values of N2 and O2 because these two gases make up 99% of the gases in air? O Yes O No
3. The Milky Way's Dark Matter Halo The Milky Way's rotation curve is approximately a constant, v(r) ~220 km/s, for 5 20 kpc, This constant circular velocity cannot be explained by the observed distribution of luminous mass Instead, we propose that the Milky Way is embedded in a roughly spherical dark matter halo. (a) Calculate M(r), the enclosed mass of the spherical dark matter halo as a function of r in the range 5< T < 20 kpc, assuming the...

Part A The rate constant for a certain reaction is k = 6.30×10−3 s−1 . If the initial reactant concentration was 0.150 M, what will the concentration be after 9.00 minutes? Express your answer with the appropriate units. Part B A zero-order reaction has a constant rate of 4.90×10−4 M/s. If after 60.0 seconds the concentration has dropped to 2.50×10−2 M, what was the initial concentration? Express your answer with the appropriate units.
The rate constant for a certain reaction is k = 9.00 times 10^-3 s^-1. If the initial reactant concentration was 0 800 M, what will the concentration be after 4 00 m minutes? Express your answer with the appropriate units A zero order reaction has a constant rate of 2.10 times 10^-4 M/s. If after 65.0 seconds the concentrator has dropped to 2.00 times 10^-2 M, what was the initial concentration?
