1. The problem states that the experiment requires a ratio of 12 parts vinegar to 1 part baking soda. 2. This means the ratio vinegar:baking soda should be $12:1$. 3. Let's check each option by writing the ratio vinegar to baking soda and simplifying it: - Option 1: $1g$ vinegar : $12g$ baking soda $$\frac{1}{12} = \frac{1}{12}$$ This ratio is $1:12$, which is not $12:1$. - Option 2: $12g$ vinegar : $6g$ baking soda $$\frac{12}{6} = \frac{\cancel{12}}{\cancel{6}} = 2$$ This ratio is $2:1$, which is not $12:1$. - Option 3: $0.5g$ vinegar : $6g$ baking soda $$\frac{0.5}{6} = \frac{0.5}{6} \approx 0.0833$$ This ratio is approximately $1:12$, but vinegar is less than baking soda, opposite of $12:1$. - Option 4: $24g$ vinegar : $2g$ baking soda $$\frac{24}{2} = \frac{\cancel{24}}{\cancel{2}} = 12$$ This ratio is $12:1$, which matches the required ratio. 4. Therefore, the correct ratio for the experiment is $24g$ vinegar to $2g$ baking soda. Final answer: $24g$ vinegar : $2g$ baking soda
