A process unit involves 3 chemical components. How many mass balances

1.	A process unit involves 3 chemical components. How many mass balances can be written?(a) 3(b) 5(c) 6(d) 4I had been asked this question in an online interview.I'd like to ask this question from Material Balance Numericals in section Material Balance of Bioprocess Engineering
Answer» The CORRECT option is (d) 4 The best explanation: We can write 4 BALANCE equations: A TOTAL balance equation and 3 component balance equations. Independent balances: Not all balances are independent SINCE the total balance is the SUM of all of the component balances. Thus, the number of independent balances we can write = the number of components.
