Well, it's gonna be twice the number of moles of carbon monoxide, twice this number right over But this is not the equation you need, as the question explicitly states, that the combustion products are carbon and water. But 6.022 1023 is 1 mol, while 12.044 1023 is 2 mol (and the number is written that way to make this more obvious), so we can simplify this version of the equation by writing it as, \[2 \;mol\; \ce{H_2} + 1\; mol\; \ce{O_2} 2 \;mol\; \ce{H_2O} \nonumber \], We can leave out the word mol and not write the 1 coefficient (as is our habit), so the final form of the equation, still balanced, is, Now we interpret the coefficients as referring to molar amounts, not individual molecules. Suppose we want to use larger numbers. Chemistry, 28.10.2019 19:28, maledabacuetes. Yep, you can do exactly that. But we can imagine that if we had more precise measurements which allowed us to use more sig figs for our answer, like four, then yes we would see an error in our answer if we rounded prematurely.
