H.W2: A tank contains (400 L) of brine made by dissolving (20 kg) of salt in water. Salt watercontaining (0.75 kg) of salt per liter runs in at the rate of (2 L/min) and the well-stirredmixture runs out at the same rate of (5 L/min). Find the amount of salt in the tank after15 minutes.

dVindt = 2 L/min (Volume in rate)dVoutdt = 5 L/min (Volume out rate)Therefore, Net dVdt =…
