The well-stirred tank of volume V = 2 m3 shown in figure is initially filled with brine, in which the initial concentration of sodium chloride at t = 0 is c0= 1 kg/rn3. Subsequently, a flow rate of Q = 0.01 m3/s of pure water is fed steadily to the tank, and the same flow rate of brine leaves the tank through a drain. Derive an expression for the subsequent concentration of sodium chloride c in terms of c0, t, Q, and V. Make a sketch of c versus t and label the main features. How long (minutes and seconds) will it take for the concentration of sodium chloride to fall to a final value of cf = 0.0001 kg/rn3?

Determine the mass of carbon dioxide (in g) produced from the complete combustion of 1.40×10-2 g of C6H10 with excess oxygen.
Pure colored substances mostly exhibit a single peak (i.e. max) in the visible; therefore the simple rules of complementary colors apply. Mixtures are a little more complicated.
