Question

Given the reaction below, if 0.003 g of carbon dioxide is used up, how many grams of oxygen will be produced? (show work)

6 CO2 + 6 H2O → C6H12O6 + 6 O2

Answer 1

Stoichiometry: 6 CO2 (reactant) = 6 O2 (product)
Every 6 CO2 (atoms, moles, etc…) that react will wield 6 O2 (atoms, moles, etc…)
0.003g CO2 * (6 O2 / 6 CO2) = 0.003g O2
