I believe the question is asking, for the same mass of HCl and CO2, comparatively, how many moles of each molecule do you have.
Steps
- Pick a mass in grams that is simple (ex. 10, 100, 5). Regardless of which mass you pick, the answer should be the same, because you are comparing the ratio of moles.
- Example: Basket A has 1 apple and 1 pear and it weighs 10g. Basket B has has 2 peaches and 1 strawberry and it weighs 20g. If you have 40g of each basket, what is the ratio of basket A to basket B. Convert the mass to the number of baskets you would have. You would make 4 Basket A and 2 basket B. The ratio is 4 basket A / 2 basket B or 2:1 simplified.
- Let's change the weight now to 70g of each basket. You would have 7 basket A and 3.5 basket B. The ratio is 7 / 3.5 = 2:1.
For the question let's follow these steps.
- Let's pick 10g for this example
- Convert 10g of HCl to mol of HCl. (HCl molar mass 36.458 g/mol)
- Convert 10g of CO2 to mol of CO2 (CO2 molar mass 44.01g/mol)
- Compare the ratio of mol of HCl to CO2. --> mol of HCl / mol of CO2
- Simplify the ratio if possible.
