Given the reaction: c6h12o6 + 6o2 → 6co2 + 6h2
how many molecules of c6h12o6(s ) are needed to produce 24 molecules of carbon dioxide?

=4moleculesC_6H_{12}O_6

Explanation:

Hello,

In this case, since 24 molecules of carbon dioxide, and considering the given reaction, the following stoichiometric calculation turns out helpful to determine the requested molecules of C₆H₁₂O₆ that are needed:

It is clear that Avogadro's number is needed to perform the one to six relationship between C₆H₁₂O₆ and CO₂.
