Measurements have shown that the concentration of salt in seawater is 35.5·gL−1. Calculate the volume in liters of seawater that must be evaporated to recover 0.0500kg of salt.Round your answer to 3 significant digits.

In a tank 100 liters of brine solution containing 50 kg of total dissolved salt. Pure water is allowed to run into the tank at the rate of 3 L/min and brine solution runs out at the rate of 2 L/min. The solution is kept stirred to make the concentration uniform. Compute the kg of salt in the tank after 1.0 hour.Question 6Select one:A.13.59 kgB.19.35 kgC.19.53 kgD.15.93 kg

A tank contains 3,000 L of brine with 15 kg of dissolved salt. Pure water enters the tank at a rate of 5 L/min. The solution is kept thoroughly mixed and drains from the tank at the same rate. How much salt is in the tank after 60 minutes?

A geochemist measures the concentration of salt dissolved in Lake Parsons and finds a concentration of 56.77·gL−1. The geochemist also measures the concentration of salt in several nearby non-isolated lakes, and finds an average concentration of 4.60·gL−1.Assuming the salt concentration in Lake Parsons before it became isolated was equal to the average salt concentration in nearby non-isolated lakes, calculate the percentage of Lake Parsons which has evaporated since it became isolated.Round each of your answers to 3 significant digits.

Ten liters of 25 % salt solution and 15 liters of 35 % salt solution are poured into a drum originally containing 30 liters of 10% salt solution. What is the per cent concentration of salt in the mixture?
