Question

7. A liquid mixture flows into a tank mounted on a balance. The composition of the mixture is 40.0 wt% n-octane and the balance is n-decane. When the mass in kg indicated by the scale is plotted against time, the data fall on a straight line that passes through the points (t = 3 min, m = 150kg) and (t = 10 min, m = 250kg).

a) Estimate the volumetric flow rate of the liquid mixture. Assume volume additivity.

            b) What does the empty tank weigh?
