An aqueous solution with chlorine 30 g/L and an organic compound with no chlorine at the rate 50 L/min were put into an extraction machine and produced aqueous solution with chlorine 5 g/L and organic compound with chlorine 10 g/L, what is the rate of aqueous solution?

Here are some steps for solving material balance problems: Draw a diagram: Sketch a simple diagram of the process. Write chemical equations: If applicable, write the chemical equations involved. Select a basis: Choose a basis for calculation. Make a material balance: Generate material balance equations by making the overall material balance and individual material balances of components involved. Then, solve them simultaneously. Label the process flow chart: Draw and label the process flow chart (block diagram). When labeling, write the values of known streams and assign symbols to... Show more

Here are some steps for solving material balance problems:
Draw a diagram: Sketch a simple diagram of the process.
Write chemical equations: If applicable, write the chemical equations involved.
Select a basis: Choose a basis for calculation.
Make a material balance: Generate material balance equations by making the overall material balance and individual material balances of components involved. Then, solve them simultaneously.
Label the process flow chart: Draw and label the process flow chart (block diagram). When labeling, write the values of known streams and assign symbols to unknown stream variables.
Use a table: Keep track of information using a table.
Use matrix algebra: Matrix algebra, also known as linear algebra, is well suited to solving material balance problems. 
Material balance problems can be solved by listing and solving a series of equations, or by use of a table where information is kept track of.
