A reactor has two feed streams with the ratio of their rate as 1:9 and has O2 and O3 with the mass fraction of 0.6 and 0.4 in stream 1 and 0.2 and 0.8 in stream 2, what is the mass fraction of O2 in the product side?

Material Balances topics include: Open and closed systems, material balance chemical reaction, multiple component systems and material balances for batch and semi-batch processes. A material balance is a calculation of the quantities of materials that enter and leave a system or process. It is based on the law of conservation of mass, which states that matter is neither created nor destroyed in a process.  In a chemical system, the mass entering the system is equal to the mass leaving the system for steady-state conditions. The principles of material balance are used to determine the input... Show more

A material balance is a calculation of the quantities of materials that enter and leave a system or process. It is based on the law of conservation of mass, which states that matter is neither created nor destroyed in a process. 
In a chemical system, the mass entering the system is equal to the mass leaving the system for steady-state conditions. The principles of material balance are used to determine the input and output flows of substances to ensure conservation of mass. 

Material balances can be applied to:
The total mass or total moles of the stream
The mass of a single compound
The mass of an atomic species
The moles of a compound
The moles of an atomic species 

The principles of material balance are essential in the field of chemical engineering and catalyst activity studies. They can also be applied in the design of chemical material stirring reaction kettles.
