According to the recipe, exactly how many cups of baking soda need to be mixed with 9 1/2 quarts of white vinegar
From the above recipe
3 quarts of vinegar = 4 cups of baking soda
9 1/2 quarts of vinegar = x
Cross Multiply
3 × x = 4 × 9 1/2
3x = 4 × 19/2
x = 4 × 19/2 ÷ 3
x = 4 × 19/2 × 1/3
x = 12.666666667 cups of baking soda or 12 2/3 cups of baking soda
