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 points (t = 4 min,

m =135kg) and (t=10 min, m= 211 kg)

Estimate the volumetric flow rate of the liquid mixture. L/min

What does the empty tank weigh? N
