Rate of Reaction Help!

Having trouble with this question, dont even know where to begin!
is there an equation or something im missing? anyway heres the question:

Consider the following reaction,

C4H8 + 6O2 ----> 4CO2 + 4H2O

Calculate the rate at which water, to zero decimal places, is formed if 106 moles/min of C4H8 are fed into the reactor and 50% of the C4H8 reacts.

any help atall greatly apreciated. cheers!

Work out how many moles of water are made per mole of C₄H₈. Then you know 106 moles of C₄H₈ are made per minute but only half of that reacts thus you can work out the rate of water being made per min!!

well if 106 moles go in each minute, and 50% react, then thats 53 moles reacting every minute. and the mole ratio for C4H8 :h:

2O is 1:4 so for every 1 mole of C4H8 reacting, 4 moles of H2O is made. hence 53 x 4 = 212

so water is formed at 212 moles/min
(correct if wrong, or if i missed something)
