A liquid mixture containing 40.0 wt% -octane and the balance -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 ( 3 min, 150 kg) and ( 10 min, 250 kg).
Estimate the volumetric flow rate of the liquid mixture.
What does the empty tank weigh?
