Question

26.5g C16H34
88.0g O2
Which is the limiting reagent?

Answer 1

Write out the reaction they are undergoing and convert both masses to moles.

The limiting reagent will provide the least amount of product

Answer 2

so which ever reagent gives you the smallest amount of moles of product is the limiting reagent

Answer 3

so like 26.5 g ( I mol C16 H34)/ 226.446 g C26 H34)
????

And the same with O2?

Answer 4

26.5g/226.446 = 0.117mol
now convert to product, In this case I will convert to CO2

(0.117mol/2)*32 = 1.872mol

now do this with O2 and compare the amount of moles you get. The Reactant that gives you the least amount of moles will be your limiting reagent

Answer 5

hmm okay!!! makes more sense.
