To determine the total amount of baking soda used in recipes that specifically use exactly \( \frac{1}{4} \) teaspoons, we first need to count how many times that amount appears in the data you provided. From the list, we can see:
- The amounts of baking soda are: 1, 1, 2, 1, 1, 4, 1, 1, 1, 4, 1, 3, 4, 1, 1, 1, 4, 1, 1, 4, 1, 1, 2, 1, 1, 2
It appears that there are no recipes that used exactly \( \frac{1}{4} \) teaspoons of baking soda based on the data you provided.
Since there are no \( \frac{1}{4} \) teaspoons, the total amount of baking soda from those specific recipes is:
\[ 0 \text{ teaspoons} \]
