A 131 L mixing tank initially contains 65 L of brine solution with a concentration of 7 g/L. Brine solution with a concentration of 9 g/L flows into the tank at a rate of 7 L/min. The solution inside the tank is kept well-stirred and is discharged at the rate of 3 L/min. Determine the amount of salt, in grams, inside the tank at the moment before it overflows.
A 131 L mixing tank initially contains 58 L of brine solution with 310 g of dissolved salt. Brine solution with a concentration of 8 g/L flows into the tank at a rate of 7 L/min. The solution inside the tank is kept well-stirred and is discharged at the rate of 4 L/min. Determine the concentration of the solution, in grams/liter, inside the tank at the moment before it overflows.
