Unitary method

Molecular intyerpreation: How many O_(2) molecules react with 74 CH_(4) molecules according to the preccdign equation? Strategy: The balanced equation tells us that one CH_(4) molecule always reacts with two O_(2) molecules. Either we go for unitary method or construct a unit factor from the above fact: (2 O_(2) "molecules")/(1 CH_(4) "molecule")
