A liquid mixture containing 40.0 wt% n-octane and the balance n-decane flows into a tank mounted on a balance. 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 mm, m = 150 kg) and (t = 10 mm, m = 250 kg).

(a) Estimate the volumetric flow rate of the Liquid mixture.

(b) What does the empty tank weigh?
