Question

If you wanted a 2 to 1 molar ratio of H₂O molecules to CO₂ molecules and you had 50.0g of H₂O, how

many grams of CO₂ would you need? (Hint: It isn't 25g!)

Answer 1

To achieve a 2 to 1 molar ratio of H₂O molecules to CO₂ molecules, and given 50.0g of H₂O, you would need 33.3g of CO₂. This is calculated by dividing the mass of H₂O by the mole ratio of H₂O to CO₂ to get the required mass of CO₂.
