5. Mass Inputs = Mass Outputs At steady state there is no generation of elemental mass or moles. This is also true for inert (ie non-reactive) compounds. Balances on compounds may have non-zero accumulation terms. 6. For a system with i components there are i mass balances. The total mass balance is redundant. 7.

We have thus used 0.0280 moles of TiO2 and 0.0280 moles of FeO to make 0.0280 moles of ilmenite. Note that we have not made 0.0280+ 0.0280 = 0.0560 moles of ilmenite, because one mole of ilmenite contains one mole each of TiO2 and FeO. Next we allocate our K2O to (provisional) orthoclase. Put the 0.0097 moles of K2O in the or’ column.
